Two employees of the Pakistan Atomic Energy Commission were injured when the vehicle they were traveling in was targeted with a roadside bomb in the country's troubled northwestern region on Tuesday.
The blast occurred in Lakki Marwat district of the North West Frontier Province, officials were quoted as saying by the Geo News channel. A technician and the vehicle's driver were injured in the attack, they said.
Both men sustained minor injuries and were taken to a nearby hospital. The windows of the vehicle were shattered by the blast. No group has claimed responsibility for the attack. The PAEC has several important installations in the Lakki Marwat area, including a uranium mine.
Militants have carried out a series of audacious attacks on government installations and civilian targets since the army launched an operation against the Taliban in South Waziristan tribal region in October.
Terrorists today targeted Pakistan's powerful Inter Services Intelligence for the second time in less than a month, as suicide bombers struck its office in Multan by detonating their vehicle, which was packed with up to 1,000 kg of explosives. At least 12 people were killed and 47 injured in the attack. The attack in Multan follows the suicide blast at a crowded market in Lahore on Monday night that killed 49 people and injured 180 others.
Another suicide bomber blew himself up outside a court complex in Peshawar on Monday, killing ten people.
