Israel and Iran traded fire Monday in their first attacks since the U.S. struck a ceasefire with Tehran two months ago.

Kuwait briefly shut its main airport Wednesday after Iranian drones heavily damaged a passenger terminal, killed one person and wounded dozens — the latest in back-and-forth attacks by Iran and the U.S. that test a fragile ceasefire.

Trump said in a social media post that military officials told him "the Iranians shot down one of our highly sophisticated Apache Helicopters." He added that both service members "are safe and uninjured."

In a statement posted to social media, U.S. Central Command said the strikes would be "a proportional response to unjustified Iranian aggression."

The United States said Monday that it bombed radar and drone sites in Iran after Tehran shot down an American drone over the weekend. Iran then said it targeted American soldiers in Kuwait with missiles, which the U.S. says it shot down.

The latest wave of strikes come hours after President Donald Trump said Iran would “pay the price” for taking too long to negotiate a peace deal.

Trump said in a social media post that he made the move after a breakthrough in negotiations, and that significant points under discussion "have been brought to the highest level of Iranian leadership and approved."

President Donald Trump said in a social media post that the U.S. would hit Iran "VERY HARD TONIGHT" and would "assume total control" of Iran's oil and gas industries, including the key Kharg Island oil terminal, in the "not too distant future."

President Donald Trump's warning came hours after Bahrain, Kuwait and Jordan — all of which host U.S. troops — came under Iranian fire.

The reports by the Fars and Tasnim news agencies, both believed to be close to Iran's paramilitary Revolutionary Guard, come as Iran insists the fighting in Lebanon is part of the wider ceasefire talks with the U.S. over the war.
