Islamic militants used suicide car bombs and grenades to attack the U.S. consulate in the Pakistani city of Peshawar Monday, killing at least five people.
Pakistani Taliban militants claimed responsibility for the attack that left several others wounded.
Security officials say militants detonated car bombs outside the consulate and fired grenades and other weapons as they tried to enter the building. Police quickly closed off the area and were able to stop the militants from getting inside the consulate.
White House Press Secretary Robert Gibbs condemned the attack and said the White House is greatly concerned.
A statement from the U.S. Embassy in Islamabad said at least two Pakistani security officers were killed. There are no reports that any U.S. citizens were among those wounded or killed in the attack.
Earlier Monday, authorities say a suspected suicide bomber killed at least 40 people and wounded scores of others at a political rally in the Lower Dir district.
The Awami National Party (ANP), which heads the ruling coalition in North West Frontier Province, was meeting to discuss a name change for the province.
The ANP has supported military operations against the Taliban and Islamist militants in the country.
The two attacks in northwestern Pakistan took place just hours before Pakistani President Asif Ali Zardari addressed the national parliament in Islamabad and vowed to defeat militancy.
