Suspected Islamist militants blew up a police vehicle in northwestern Pakistan, killing seven people.
They included three policemen and three paramilitary troops. A passerby was among the dead and hospital officials said five people were wounded, including two women.
The vehicle was on a routine patrol on the outskirts of the town of Dera Ismail Khan when the bomb apparently planted in a dusty road exploded as it passed over.
Dera Ismail Khan is close to the Waziristan tribal region where security forces have been battling al Qaeda-linked militants and their local supporters over the past two years.
No one claimed responsibility for the attack but Interior Minister Aftab Ahmed Khan Sherpao said Islamist militants were likely behind the blast.
A few hours later, a second bomb went off near the site of the first blast. A wall of a nearby government building collapsed, but there were no casualties.
