United Nations (Agencies): Expressing shock over use of minor in a suicide bomb attack in Pakistan, UN Secretary-General Ban Ki-moon condemned the incident, which killed about 31 soldiers.

"The secretary-general strongly condemns suicide bombing at an army recruitment centre at Mardan and he was appalled by the reported use of a minor to commit this terrorist act," UN spokesman Martin Nesirky informed.

The minor, disguised as a schoolboy, blew himself up at a Pakistan Army training centre. The suicide attack targeted a military parade at Punjab regiment centre in Mardan, which is about 50 km northeast of Peshawar, the capital of Khyber Pakhtunkhwa province.

The secretary-general extended his condolences to the families of the victims and to the government of Pakistan.

Taliban claimed responsibility for the attack and the group's spokesman Ihsanullah Ihsan threatened of more attacks to avenge the US drone strikes and operation by security forces in tribal regions in Pakistan, reports said.
