'Suicide bomb' hits Kabul hospital

At least three people have been killed in an explosion at a military hospital in the Afghan capital, Kabul, the Afghan defence ministry says.

An Afghan intelligence official told the BBC that two suicide attackers had got inside Charsad Bestar Hospital.
One blew himself up in the hospital canteen while the other was somewhere in the facility, he said.
A doctor said: "As soon as the explosion took place, everyone started running from the cafeteria area."
He added: "It was a lunch-time. We have been locked inside our rooms and departments because the other attacker is still somewhere."
The 400-bed Charsad Bestar Hospital was built in the 1970s. It treated soldiers wounded during the Soviet occupation, people injured in the civil war that followed their retreat and, more recently, senior Taliban and al-Qaeda commanders.
After the fall of the Taliban, Western countries invested millions of dollars in the hospital, upgrading its facilities and installing state-of-the-art medical equipment and supplying air ambulances.
The BBC's Bilal Sarwary in Kabul says that security is kept very high at the facility.
