At least seven people have died after militants attacked the US consulate in the north-western Pakistani city of Peshawar.There were several explosions in the area near the consulate and buildings collapsed. A gun battle between police and the attackers followed.
Pakistan's main Taliban faction said it had carried out the raid.
The raid came hours after 43 people died in a suicide attack about 80 km (50 miles) north-east of Peshawar.
The bomber targeted a crowded rally held by a Pashtun nationalist party in Timergara, Lower Dir.
'Great concern'
Investigators suspect it was co-ordinated with the Peshawar attack, in which police told the BBC four militants and three security personnel died.
There were no reported US casualties and it is not clear if the US consulate building suffered any damage.
The White House condemned the attack and expressed "great concern".
Officials said the attack was well organised, but order had been restored.
The militants struck near Shama Square, a major crossroads at the northern end of Peshawar's cantonment area, near the US consulate.
'Miscreants'
There are also some army barracks and offices of the army's Military Intelligence in the vicinity.
An Associated Press reporter at the scene said two of the explosions were just 20m from the consulate, which is in a heavily fortified area.
Pakistani police officer Ghulam Hussain told AFP news agency: "The target was certainly the American consulate but they didn't succeed in getting there.
"One of the suicide bombers blew himself up close to the gate. Police guarding the US consulate started retaliatory fire.
"More blasts took place. We have recovered unexploded material from four different points," he said.
Taliban spokesman Azam Tariq said his group had carried out the raid.
"Americans are our enemies. We carried out the attack on their consulate in Peshawar. We plan more such attacks," he told Reuters news agency.
Pakistani Prime Minister Yousuf Raza Gilani condemned the bombers as "miscreants trying to spread panic", reports AFP.
TV footage showed army soldiers taking battle positions on the main Khyber Road where the blasts took place.
Witnesses told BBC Urdu a couple of armoured vehicles parked outside the consulate caught fire.
"I saw attackers in two vehicles. Some of them carried rocket-propelled grenades," Peshawar resident Siraj Afridi told Reuters.
The BBC's Shoaib Hasan in Islamabad says that this is the first successful attack against a US facility in Pakistan target in four years.
In 2006, a US diplomat was killed by a suicide car bomber near the US consulate in Karachi, days before a visit to Pakistan by then US President George W Bush.
Peshawar, which is on the edge of Pakistan's tribal areas, has been frequently targeted by Islamist militants.
Analysts say the attacks appear to be in response to a major security operation launched in the Orakzai tribal region near Peshawar last week.
