Wearing school uniform, a boy aged 14 or 15 blew himself up at a recruitment parade inside a heavily guarded military compound just outside the town of Mardan.
Teenage suicide bomber kills 31 Pakistani army recruits
MARDAN // A teenage suicide bomber killed up to 31 Pakistani army recruits at a parade ground today, an attack the Taliban said was revenge for US drone strikes and local military offensives.
Wearing school uniform, the teenager blew himself up at the parade inside a heavily guarded military compound just outside the town of Mardan, killing the soldiers with shrapnel and explosives, officials said.
It was the deadliest suicide bombing in Pakistan since a woman with a bomb strapped under her burqa killed 43 people at a UN food distribution point on Christmas Day in the tribal district of Bajaur.
The Taliban claimed responsibility and threatened "bigger attacks" in coming days to avenge American drone strikes and Pakistani military operations targeting Islamist militants in the northwestern tribal belt.
Abdullah Khan, a senior police officer in Mardan, around 30 kilometres (20 miles) from the regional capital Peshawar, told AFP: "It was a suicide attack. The teenager bomber was on foot and was wearing a school uniform.
"The death toll has now reached 31 recruits. Thirty-six have been injured, Sixteen of them are critical," Mr Khan sai.
"The bomber was 14 or 15 years old. He was not a student at the school inside the regiment. He came from outside but was dressed like the other school boys."
After the attack, soldiers in bulletproof jackets and helmets cordoned off the entire area around the Punjab Regiment Centre, deploying jeeps mounted with machine guns and preventing access to the site, an AFP reporter said.
Police had earlier put the death toll at 27.
Pakistan suffers near-daily attacks blamed on Taliban and al Qa'eda-linked militants. The attacks have killed more than 4,000 people since government troops evicted Islamists from an Islamabad mosque in a deadly siege in July 2007.
Most of the violence is concentrated in the northwest, where Washington has branded the lawless tribal belt snaking along the border with Afghanistan the global headquarters of al Qa'eda and the most dangerous place on Earth.
A suicide attack at the same army base in Mardan killed at least 42 soldiers in 2006 and another attack nearby killed 13 people in 2008.
Pakistan is under pressure to eliminate militant sanctuaries to help US efforts to win the war against the Taliban in Afghanistan and defeat al Qa'eda.
But attacks on police and soldiers have spiked since the start of a fresh offensive in the tribal district of Mohmand, where the United Nations has said around 25,000 people have fled the fighting. Mardan is around 50 kilometres east of Mohmand.
Taliban spokesman Azam Tariq told AFP by telephone from an undisclosed location: "We proudly claim this suicide attack.
"We will continue such attacks on those people who are providing security to the Americans. These attacks are to avenge the drone attacks and military operations in the tribal areas."
Relations between Pakistan and the United States have sunk to a new low since a US official shot dead two men in the eastern city of Lahore last month, and was taken into Pakistani custody under investigation for double murder.
Raymond Davis said he acted in self-defence, fearing the men were about to rob him. Washington says he has diplomatic immunity and should be released immediately.
Pakistan's interior minister, Rehman Malik, has confirmed the American had a diplomatic passport, but the government says the matter stands with the courts, where lawyers argue that diplomatic immunity should be be waived in the case of grave crimes.
The military announced separately today it had successfully test fired a cruise missile capable of carrying nuclear and conventional warheads.
The Hatf 7 (Babur) had a range of 600 kilometres and could carry conventional and other warheads, it said.
