A suicide bomber dressed in school uniform has killed at least 20 soldiers at an army recruitment centre in north-west Pakistan.
The teenager struck as recruits were doing physical training on the parade ground at the Punjab Regiment Centre in the town of Mardan on Thursday.
He was wearing the uniform of a school in the area, the BBC reports.
A Taliban spokesperson has claimed responsibility for the bombing.
A bomb attack on the same centre in 2006 killed at least 20 soldiers.
There has been an increasing use of teenage bombers in the country. Pakistani troops have found whole camps in the north-west where children as young as 10 were being trained to become suicide attackers, the BBC reports.
