The anger of the crowd at the funeral for fighters killed in the two-day long Israeli operation highlighted the deep unpopularity of the Palestinian Authority and the widening rifts among different Palestinian factions.

The three members of the central committee of Abbas’ Fatah party were driven away as thousands of mourners turned on them, chanting “Get out! Get out!”.

The 87-year-old Abbas, who has rebuffed pressure to step down, visited the cemetery where the funeral was held, at the entrance to the Jenin refugee camp.

Flanked by his special presidential guards, he addressed the crowds at the edge of the camp, where torn-up streets and burnt out buildings bear witness to the intensity of the biggest Israeli operation in the occupied West Bank in 20 years.

“The heroic Jenin camp stood against the aggression sacrificed its casualties and offered all it has for the sake of the homeland,” Abbas said.

He told the cheering crowds that the camp will be rebuilt.

While Abbas has condemned the Israeli raid on Jenin and announced he was suspending a security cooperation accord with Israel, many Palestinians feel his position has been hopelessly compromised as violence across the West Bank has spread.

“Where were they all those years?” said one man in the camp, who declined to give his name for fear of reprisals by security forces. “They don’t care about us.”

For well over a year, Israeli raids in cities like Jenin or Nablus have become routine. Hundreds of Palestinians, most fighters but many civilians as well, have been killed, while a spate of Palestinian attacks have killed dozens of Israelis.

The Palestinian Authority, set up following the Oslo peace accords three decades ago, exercises limited governance over parts of the West Bank, including Jenin but it has been powerless to stop Israeli raids or control militant groups.

Palestinian Authority security forces, including members of Abbas’ own presidential guard unit, have been deployed in large numbers in Jenin after the tensions with other factions burst out into the open during the funeral last week.

Hamas, the Islamist movement that controls Gaza and the Iranian-backed Islamic Jihad, have long been been at odds with the Palestinian Authority but Abbas has also faced growing criticism from within his own party Fatah, which also has an armed wing that is active in Jenin.

Paving had been churned up by armoured bulldozers, causing a water pipe to burst and leaving sodden gullies of rubble that residents – many of whom had holed up at home, or evacuated as a precaution – traversed with a grim and businesslike gait.

After months of spiralling skirmishes with Jenin’s gunmen, Israel on Monday swamped the city’s refugee camp with hundreds of commandos backed by combat drones. Commanders said the operation – dubbed “Home and Garden” – aimed to root out Palestinian militant infrastructure.

“They did not get what they wanted, thank God. The youths are fine, the families are fine and the camp is fine,” Mutasem Estatia, a father of six, told Reuters after what he described as two nights being kept away, one of them in Israeli detention.

Twelve Palestinian men or male teenagers were killed, five of them confirmed fighters from the Hamas or Islamic Jihad factions. Scores of Palestinians were wounded. The army – which lost a soldier in the clashes – said it killed combatants only.

Israeli forces also detained around 150 suspected militants and destroyed caches of guns and roadside mines – including an arsenal under a mosque – and a command centre, the army said.

“There are 12 martyrs and we are proud of them, but we expected more damage given the raid’s scale,” Estatia said.

Israel appeared poised to return to Jenin and other areas of the occupied West Bank, where Palestinians seek statehood.

“I’ve made clear that this broad action in Jenin is not a one-off,” Prime Minister Benjamin Netanyahu told Channel 14 TV on Monday. “It will be the beginning of regular incursions and continuous control of the territory and that’s why there’ll be no safe haven for terrorism.”

As the troops withdrew overnight, Israel reported a volley of rockets from the Gaza Strip, another Palestinian territory. The rockets were shot down and Israel’s air force struck targets in Gaza belonging to the ruling Hamas, causing no casualties.

In a further sign of violence spilling over from Jenin, a Palestinian rammed his car into pedestrians in Tel Aviv on Monday and went on a stabbing spree, wounding eight people before he was shot dead. Hamas claimed him as a member.

“We say to the enemy: The time when you could practice your aggression against our people without paying the price has passed. Today, Jenin is teaching you a lesson in resistance and steadfastness,” Hamas leader Ismail Haniyeh said in a statement.

The tenement-like camp houses refugees from the 1948 war of Israel’s founding. Poverty, frustrated peace diplomacy and political drift have stoked support for Iranian-backed groups like Islamic Jihad and Hamas, which preach Israel’s destruction.

Marshoud was named by the militant Islamic Jihad group as one of four of its members killed on Monday during Israel’s assault in Jenin refugee camp.

Grieving relatives stroked his face as his body laid wrapped in a shroud at a nearby hospital.

Marshoud’s father, Hussam, said the last time he saw his son, he had been rushing to the hospital after hearing that a friend had been injured. “He was saying: ‘I want to go to the hospital …’ I had a feeling that something would happen.”

At least 11 Palestinians have been killed during Israel’s operation that began on Monday, one of its biggest in the West Bank in years. Several of the dead were reported to be in their teens: the Iran-backed Islamic Jihad said that alongside Marshoud, fighters aged 17, 18, and 19 were killed.

Their ages underline the youth of many of those caught up in spiralling violence in the West Bank areas such as Jenin, where jobs are hard to find and hopes for the future have been dimmed by the bleak outlook for the moribund peace process.

Israel says the operation aimed to destroy infrastructure and weapons of militant groups at the camp, where some 14,000 people live in cramped alleyways that have long been a stronghold of Palestinian armed groups.

Israel says there have been about 50 shooting attacks on Israelis since the start of the year by people from the Jenin area. The Israeli military has said it had confirmation of nine Palestinians killed by its forces, saying all were combatants.

Hamas, the Islamist group that governs the Gaza Strip, says one of its members was killed. There was no immediate confirmation from Palestinian sources as to whether the other six fatalities – including males aged 17 to 23 – were combatants or civilians.

The deaths add to the toll of a wave of violence that has cost the lives of more than 190 Palestinians, including both fighters and civilians, and 25 Israelis and foreigners since the start of the year.

Stranded Amid Violence

Jenin refugee camp has emerged as a flashpoint during a wave of Israeli-Palestinian violence, with deadly confrontations a regular occurrence.

The camp was also the scene of some of the worst violence during the second Intifada, which began after the failure of U.S.-backed peace talks in 2000 and mushroomed into an armed conflict between Israel and Palestinian militant groups.

In 2002, Israel launched a major assault in the camp, part of a wider West Bank operation which Israel said aimed to stop militant attacks including suicide bombings which killed hundreds of Israelis.

The Palestinian Red Crescent said it had evacuated 500 families, or around 3,000 people, from the camp in the latest assault, which involved hundreds of Israeli troops and drones.

Jamal Hamdan held his sister’s hand as they walked quickly out of the camp on Tuesday morning during a lull in the violence. “I came yesterday evening to take my sister to my home, but we were stuck,” he said.

Residents of the camp took stock of the damage including roads which had been badly damaged by bulldozers.

U.N. aid agencies voiced alarm at the scale of the Israeli operation. A spokesperson for the U.N. humanitarian office said damage to infrastructure caused by air strikes had cut off most of the water and electricity at the camp.

Fearing for his family’s safety, Jihad Hassan said he fled his home after his neighbour’s house was hit, wounding his son in the leg.

“We are waiting to return to our home. It is something, when a person is forced to leave their home,” said Hassan, 63, speaking at the hospital where his son was being treated.

“The rockets did not pose a threat to communities in the area,” a military statement said.

It said the rockets travelled some 80 meters (265 feet) and added that these were “were makeshift rockets, with very limited capabilities”.

Intense gun battles between Israeli forces and Palestinian militants occurred in Jenin earlier this month that left seven Palestinians dead, part of an upsurge of violence in the Israeli-occupied West Bank.

Separately on Monday, the military said one of its drones fell in Lebanese territory during routine activity. A media channel affiliated with Lebanon’s Hezbollah said on Monday the powerful armed group shot down the drone
