The U.S. military says it is striking targets in Iran.

This comes after a month with no military action between the two countries.

U.S. Central Command said the strikes follow recent attacks by Iran’s Revolutionary Guard against commercial shipping in the Strait of Hormuz.

It also cited attacks against American service members in the region.

On Sunday, the U.S. struck rocket launchers on Larak Island.

Iran then launched missiles at U.S. sites in Jordan, which were intercepted.

The United Arab Emirates said it stopped an Iranian drone over its waters.

President Donald Trump said Monday that more strikes might be needed.

He claimed U.S. and Israeli bombardment has left Iran "a failed nation."

He said much of Iran's leadership has been killed, its economy is weak, and its military is devastated.

Still, Trump acknowledged more action could come.

"We'll see what happens," he told reporters.

The U.S. and Iran have fought intermittently for over six months.

The recent lull lasted a month.

Iranian state TV reported explosions in the port city of Bandar Abbas.

The U.S. military says its attacks are limited and precise.

It says they aim to stop Iran from placing new mines in the Strait of Hormuz.
