A terrorist attack near the U.S. Consulate in Peshawar, Pakistan, killed two consulate security guards and at least four others Monday, authorities said.
The two consulate employees who died were Pakistani, the U.S. Embassy in Islamabad said, and "a number of others were seriously wounded."
At least six people were killed in all, a government official said.
All U.S. citizens were accounted for, and some had minor injuries, State department spokesman P.J. Crowley said.
The coordinated attack involved a vehicle suicide bomb and attackers who tried to enter the consulate by using grenades and weapons fire, the U.S. Embassy said in a statement.
"They were well-organized. They were well-equipped," he said of the attackers.
The three explosions went off within a span of 15 minutes in the area of Saddar and Hayatabad Avenue, near the American consulate and the Peshawar headquarters of Pakistan's intelligence agency, which was the target of a deadly car bomb attack in November.
