The U.S. embassy in Qatar on Monday recommended that Americans stay indoors until further notice for safety reasons amid the Israel-Iran conflict.

“Out of an abundance of caution, we recommend American citizens shelter in place until further notice,’’ the advisory said.

The advisory came after the U.S. strikes against three Iranian nuclear sites in Natanz, Fordo and Isfahan in the early hours of Sunday.

U.S. President Donald Trump said after the attack that Tehran “must now agree to end this war’’ or face far more serious consequences.

Iranian Foreign Minister Abbas Araghchi said the door to diplomacy should always be open, but added that now was not the time.

He accused the U.S. of undermining diplomatic efforts and affirmed Iran’s commitment to safeguarding its security and interests.

The Atomic Energy Organisation of Iran said the attacks would not halt its nuclear industry’s progress.

The U.S. strikes drew widespread international condemnation.

UN Secretary-General Antonio Guterres described them as a dangerous escalation and a threat to global peace.

Russia strongly denounced the attacks, calling them a gross violation of international law, the UN Charter, and UN Security Council resolutions, and urged the IAEA to respond impartially.

Cuba and China also condemned the U.S. operation.
