In a statement, Iran’s Foreign Ministry said the latest U.S. attacks on coastal surveillance installations breached the memorandum of understanding reached by both sides to halt hostilities.

“These brutal attacks, which targeted Iranian coastal surveillance facilities, are a blatant violation” of the peace agreement, the ministry said.

The U.S. military said its forces launched strikes on Friday against Iranian missile and drone storage facilities, as well as coastal radar sites, describing the operation as a response to an Iranian attack on a cargo vessel transiting the strategic Strait of Hormuz.

The exchange marks the latest escalation despite ongoing diplomatic efforts to preserve the ceasefire framework established after weeks of conflict. The competing accounts underscore the continuing tensions between Washington and Tehran over the implementation of the agreement.

Neither side indicated that formal negotiations had been suspended, but the latest military actions have raised fresh uncertainty over the durability of the peace arrangement.
