Islamabad, Pakistan CNN —  

Gunmen in the restive Pakistani province of Balochistan on Thursday shot and killed five Shiite Muslims traveling in a van and two U.N. employees, local officials said.

Armed men riding motorbikes opened fire on the vehicle in the outskirts of the city of Quetta, killing five people and wounding four others, said Qazi Abdul Wahid, a senior police official in the city.

Wahid said he believed the attack was an act of “sectarian terrorism.”

In a separate eruption of violence, two armed men on a motorbike fired on a vehicle of the U.N. Food and Agriculture Organization in the district of Mastung, said Munir Shahwani, a local police official. Mastung is about 50 kilometers from Quetta.

The attack killed two aid workers and wounded one, Shahwani said, adding that the workers were local Pakistanis employed by the organizations.

Balochistan, Pakistan’s largest province, lies along the border with Iran and Afghanistan, and has seen frequent violence between suspected militants and security forces.
