A gunman has shot dead two senior American military officers inside the heavily guarded Afghan interior ministry in Kabul. Reports say those killed are a colonel and a major, and the gunman escaped. The Afghan defence minister has apologised for the killings, and a Pentagon statement said the United States condemned the attack in the strongest possible terms. Jonathan Blake reports from Washington.
The reaction from Washington has been strong and swift. The Department of Defence says the killings are unacceptable and are condemned by the United States in the strongest possible terms. The Pentagon says the Afghan defence minister called his US counterpart Leon Panetta to offer his condolences and apologise. Now the US is urging the Afghan government to take action to protect Nato forces after what it described as "a challenging week in the country".
The Taliban said they shot the Americans in retaliation for the burning of copies of the Koran by soldiers at a US base last week.
Reports from Pakistan say the authorities have started demolishing the compound in the garrison city of Abbottabad where Osama bin Laden was killed by American forces last year. Ilyas Khan reports from Islamabad.
Residents have told the BBC that a curfew has been placed on the people in the area, and they have been asked not to leave their homes. But many are reporting seeing and hearing bulldozers and diggers at Osama bin Laden's former compound. The demolition started early in the evening and is still said to be continuing. The site is a large compound with several high walls built around the actual house. The former al-Qaeda leader was killed in a secret US operation there last May.
Syrian activists say at least 41 civilians and 16 soldiers have been killed in the latest violence across the country during the day. The figures cannot be independently verified. Jim Muir reports from neighbouring Lebanon.
In Khalidiya, a district of Homs close to Baba Amr, which has also been heavily bombarded recently, thousands of mourners packed a square and chanted anti-regime slogans as six coffins were paraded around in a circle. They were of people killed in the latest violence. At Baba Amr itself, hundreds of armed rebels from the Free Syrian Army are holding out against siege and bombardment by security forces. Throughout the day, International Red Cross and Syrian Red Crescent officials tried to negotiate another evacuation of seriously wounded people, but by the end of the day, the talks have failed to produce results.
