The U.S. embassy in Yemen reopened on Tuesday, an embassy official said.
"We are reopened," a U.S. embassy official said.
The embassy had closed on Sunday over "security concerns".
The British and French embassies resumed operations on Tuesday but remained closed to the public, diplomats at those missions said.
Yemeni forces killed at least two suscpected al Qaeda members on Monday they said were behind the "threat" that forced the foreign embassies to close.
