A bomb attack on Thursday killed at least two Pakistani oil workers in a remote town in the country\'s troubled southwest that borders Afghanistan and Iran, police and doctors said. The blast hit a convoy of Pakistan\'s government-run Oil and Gas Development Company (OGDCL) in the mineral rich province of Baluchistan, where rebels are fighting for autonomy and demanding a greater share of natural resources. \"We received two dead bodies and seven injured from the blast site,\" Siddiq Ahmed, a doctor told AFP by telephone from the local district hospital in the town of Jafarabad, where the attack took place. Police said the bomb was fixed to a motorbike and parked on the roadside about 170 miles (272 kilometres) southeast of the provincial capital Quetta. \"It was a remote-controlled device which hit the oil and gas officials\' vehicle,\" Mohammed Tariq, a senior police official, told AFP. Baluchistan is riven by Islamist militancy, sectarian violence between majority Sunnis and minority Shiite Muslims and a separatist insurgency. Baluch rebels rose up in 2004 demanding political autonomy and a greater share of profits from the region\'s wealth of natural resources. Hundreds of people have since died. Separately a suicide bomber blew himself up in front of a vehicle of a military contractor in Kotkai village of the troubled South Waziristan tribal district bordering Afghanistan on Thursday, security officials said.
