At least 30 people die in blast at Pakistan mosque

An attackat a northwestern Pakistan mosque during Friday prayers carried out by a suicide bomber has leftat least 30 people dead, a government official said.

Upper Dir district coordination officer Atif-ur-Rehman saidmany more were wounded in the blast.

The attack is part of a wave of violence along the Afghan border in recent days just as the army says it is close to defeating Taliban militants in the Swat Valley.

No group immediately claimed responsibility for the mosque blast.

Meanwhile, four soldiers were killed by a roadside bomb in South Waziristan, on Friday, according to two intelligence officials.

South Waziristan is a tribal region bordering Afghanistan that some suspect will be the next site of Pakistani military action against the Taliban.
