Grenade injures European tourists

ISLAMABAD, Pakistan (CNN) -- At least nine European tourists and two Pakistanis have been wounded in a grenade attack in Pakistan's North West Frontier province.

CNN's Tom Mintier said that the holidaymakers were not seriously hurt after a grenade was hurled at them by an unknown assailant on Saturday.

Seven Germans and two other Europeans had been treated in hospital and then released, he said.

The incident occurred in Mansehra, about 170 miles north of Peshawar, police told The Associated Press.

Police told AP the minivan with about 21 tourists had stopped at the site of inscriptions associated with the Mauryan emperor Ashoka when the blast occurred.

The non-German European casualties were believed to be Austrians, police told AP.

In the capital Islamabad, the Interior Ministry confirmed the attack but offered no further details.

There was no immediate report on the area in Germany from which the majority of the tourists came.

The Germany Embassy has confirmed it is investigating the incident.

In May, a bomb attack at the Sheraton hotel in Pakistan's main commercial city of Karachi killed 14 people, including 11 French engineers.

Last month 12 Pakistanis died and 20 were seriously injured in a bomb attack on the U.S. consulate in Karachi.

A verdict is due this week in the trial of four men over the kidnapping and murder of U.S. journalist Daniel Pearl who disappeared in Karachi in January researching a story about Pakistani militants.
