GAUHATI, India, Oct 6, SPA -- A militant group ambushed and killed 11 people, including seven paramilitary soldiers, in northeastern India's troubled Assam state Friday, police said. In a separate incident, also in Assam, seven people were wounded when a hand grenade was thrown at a police vehicle. In the ambush, the militants opened fire on two vehicles carrying railway workers and the soldiers guarding them, said Assam state police chief D. N. Dutt. «The incident took place at 10:30 this morning,» saidDutt. «We suspect it to be the handiwork of a tribalmilitant group in the area called Dima Halam Dauga,» hewas quoted as saying by the Associated Press. The group represents the Dimasa, a small ethnic groupfighting for more autonomy. The militants operate in thearea of the attack, some 360 kilometers (220 miles) southof Gauhati, the capital of Assam. Four other railway workers were wounded in the ambush and the rebels fled with the soldiers' guns, Dutt said. In the other incident, separatist rebels in the town ofDoomdooma hurled grenades at a police vehicle, injuringthree policemen and four bystanders, authorities said. «A grenade was lobbed at a senior police officer'svehicle Thursday night ... but it missed the target andexploded seconds later,» said local government officialAbsar Hazarika. Hazarika blamed the attack on the United Liberation Front of Asom, or ULFA, which has been campaigning for Assam state's independence from India for the past 26 years. Doomdooma, about 550 kilometers (340 miles) east ofGauhati, Assam's capital, is a tea-growing area and a ULFAstronghold. The federal government unilaterally announced the truce with ULFA in August as a goodwill gesture, but canceled it after rebels attacked a police patrol and killed a tea planter in late September. At least 10,000 people, mostly civilians, have died inAssam since the insurgency began more than two decades ago.--SPA www.spa.gov.sa/394442
