Militants attacked a vehicle of an oil exploration company and killed two of its security guards in Balochistan's Gwadar district on Saturday.

Mansoor Gichki, a senior administration officer, told DawnNews that armed militants opened fire at the vehicle of a private oil exploration company in Pasni tehsil of Gwadar.

He said two private security men guarding the officials of the company were killed on the spot. The assailants escaped unhurt from the spot

"The private oil exploration company was engaged in conducting survey of the area when the vehicle of the company was attacked by miscreants," he added.

Levies and police personnel reached the incident site as an investigation into the incident went underway.

"The incident seems to be an act of targeted killing," Gichki said.

There has been no immediate claim of responsibility for the attack. Militants in the area have been attacking security forces and pro-government politicians for more than a decade.
