Egyptian security and military officials say Saudi Arabia and Egypt will lead a ground operation in Yemen against Shiite rebels and their allies after a campaign of airstrikes to weaken them.
Three senior officials tell The Associated Press that forces would enter by land from Saudi Arabia and by sea from the Red Sea and Arabian Sea.
They said Thursday that other nations will also be involved.
They would not specify troop numbers or say when the operation would start, only that it would be after airstrikes weaken the rebels and allied forces loyal to former President Ali Abdullah Saleh.
They say the offensive aims to push the rebels into negotiations on power sharing. The officials spoke on condition of anonymity because they were not authorized to talk to the press.
