US President Donald Trump has urged Israel and Iran to cease hostilities immediately amid growing concerns that renewed exchanges of fire could undermine efforts to secure a lasting peace agreement.

“Israel and Iran must immediately stop ‘shooting,’” Trump wrote in a brief message on his Truth Social platform, reports AL Jazeera .

The appeal came as Iran's armed forces announced the suspension of their military operations against Israel, while warning that any future Israeli attacks, particularly in Lebanon, would trigger a much stronger response, according to Iran's semi-official Fars News Agency.

In a statement carried by the agency, Iran's Khatam al-Anbiya Central Headquarters said the country's armed forces had delivered a “painful response” to Israel following what it described as Israeli attacks in southern Lebanon and Beirut's Dahieh district, allegedly backed by the United States.

The statement followed a series of attacks between Israel and Iran that threatened to derail diplomatic efforts aimed at ending a conflict that has weighed heavily on regional stability and the global economy.

Israel did not immediately respond to Iran's announcement. However, an Israeli military official, speaking on condition of anonymity, told Reuters that Israel remained prepared for various scenarios in Iran and was ready to continue operations for as long as necessary.

The latest developments have intensified concerns about a possible resurgence of broader regional hostilities despite ongoing international efforts to preserve the fragile ceasefire.
