Israel and Iran initially indicated backing for a ceasefire announced by President Trump, but air raid sirens soon rang out again in Israel.

The Iranian military announced the strike against Al Udeid Air Base. Qatar confirmed the attack and said there were no casualties.

President Donald Trump on Monday announced that Israel and Iran had agreed to a ceasefire, after more than a week of fighting following Israel's strikes -- and subsequent U.S. attacks -- on Iran's nuclear program.
