Saudi Arabia and Gulf region allies have launched military operations including air strikes in Yemen, officials said, to counter Iran-allied forces besieging the southern city of Aden where the Yemeni president had taken refuge.
Gulf broadcaster Al-Arabiya TV reported that the Kingdom was contributing as many as 150,000 troops and 100 warplanes to the operations.
Egypt, Jordan, Sudan and Pakistan were ready to take part in a ground offensive in Yemen, it said.
