Nato tankers attacked in Pakistan's Khyber region

Militants frequently attack Nato supply trucks

A bomb attack has destroyed two tankers in Pakistan's Khyber region, which were carrying fuel for Nato forces in Afghanistan, officials say.

A bomb was planted under one of the tankers, causing a huge explosion. The fire spread to another tanker and engulfed shops nearby, police say.

No-one has claimed responsibility for the attacks.

In Peshawar, one schoolboy was killed and seven other people injured when a bomb exploded outside a school.

Police said they were trying to determine the cause of the blast at the Police Public School - but no one has said they carried out the attack.

Taliban militants have carried out dozens of attacks across north-west Pakistan in recent months.

And correspondents say that militants also frequently target the supply lorries for US and Nato troops that travel through Pakistani territory.
