A series of four bomb blasts rocked the U.S. Consulate in the high-security-zone of Pakistani northwestern city of Peshawar during the rush-hour on Monday, witnesses said.
The blasts occurred within 20 minutes in the cantonment area, Police said.
The U.S. Consulate has not given any information so far.
Pakistan Taliban has claimed responsibility for the multiple attacks, in which at least one person was killed and eight others were injured.
TV footage showed a big blast near a roadside shop, sending thick smoke into the air. Witnesses said they saw a car exploded with a huge blast. They said an armored vehicle of the security forces was also destroyed in one of the blasts.
The security forces, which regularly patrol in the area, opened fire shortly after the blasts, witnesses said.
Police and bomb disposal squad and other relief teams have been dispatched toward the blast site.
Emergency has been declared in the hospitals in the city. The injured were shifted to the Army's Hospital and no information about the casualties was provided by the Army. Journalists were not allowed to go into the Hospital.
An army helicopter was seen flying in the area to check if any attacker was hiding in the area. The security forces made announcements, asking people to stay away from the blast sites fearing more blasts.
The blasts smashed windows of houses and offices in the area, witnesses said.
Pakistani President Asif Zardari and Prime Minister Yousuf Raza Gilani condemned the attack and said terrorists cannot stop the Government from fighting against them.
