Iran has suspended the exchange of messages and draft texts with the United States over a preliminary agreement aimed at ending the ongoing West Asia conflict.
Tehran said the decision was triggered by Israel's intensified military strikes in Lebanon, which it described as a violation of ceasefire conditions.
The move increases concerns of a broader regional escalation, with analysts warning that Iran-backed groups, including the Houthis in Yemen, could open new fronts threatening key global shipping routes such as the Bab el-Mandeb Strait.
