At least 126 people, mostly children, have been killed in a Taliban assault on an army-run school in the Pakistani city of Peshawar, officials say. <br /> <br />All six of the militants who entered the building are said to have been killed, at least one of them in a suicide blast. <br /> <br />However, the army has not declared the operation over. Most of the 500 students have been evacuated. <br /> <br />The attack is being seen as one of the worst so far in Pakistan. <br /> <br />The BBC's Shahzeb Jillani in Karachi says the militants appear to have been intent on killing as many students as possible - rather than taking hostages, as initially thought. <br /> <br />Thousands of Pakistanis have been killed in militant violence in recent years - but the latest attack has caused unprecedented shock. <br /> <br />A spokesman for the militants told BBC Urdu that the school had been targeted in response to army operations. <br /> <br />Hundreds of Taliban fighters are thought to have died in a recent military offensive in North Waziristan and the nearby Khyber area.
