At least 100 people, mostly children, have been killed in a Taliban assault on an army-run school in the Pakistani city of Peshawar, officials say.
Five or six militants wearing security uniforms entered the school, officials said. Gunfire and explosions were heard as security forces surrounded the area.
The army says most of the school's 500 students have been evacuated. It is not clear how many are being held hostage.
A Taliban spokesman says the assault is in response to army operations.
Hundreds of Taliban fighters are thought to have died in a recent military offensive in North Waziristan and the nearby Khyber area.
A school worker and a student interviewed by the local Geo TV station said the attackers had entered the Army Public School's auditorium, where a military team was conducting first-aid training for students.
Many of the casualties were reportedly caused by a suicide blast.
The BBC's Aamer Ahmed Khan in Islamabad says Pakistan is accustomed to militant violence - but the latest attack has left the country in shock.
