SRINAGAR (Agencies) - Authorities in Indian-occupied Kashmir Monday deployed thousands of police and paramilitary forces to stem demonstrations in the main city of Srinagar over the recent killings of three protesters by the Indian troops. The stepped-up security came as Srinagar and other Muslim-dominated towns were crippled by a one-day general strike called by All Parties Hurriyat Conference (APHC) Chairman Mirwaiz Umar Farooq, veteran Kashmiri Hurriyat leader Syed Ali Geelani, Jammu and Kashmir Liberation Front-R and other pro-movement leaders and organisations to protest the deaths. The occupation authorities had imposed undeclared curfew in several areas of Srinagar by deploying heavy contingents of Indian police and troops. On June 11, a 17-year old student was killed by a police teargas shell during an anti-India protest. A day later paramilitary troops beat up a protester who died in hospital on Saturday. On Sunday, a third Kashmiri was killed when paramilitary forces opened fire after mourners of the man who died on Saturday tried to set fire to a bunker. No civilian is being allowed to move. Police say a 'strict curfew is in force, resident Farooq Bangi told AFP from downtown Srinagar. Police claimed restrictions on civilian movements were being enforced to prevent the continuation of protests that have rocked the city for the past ten days. Despite increased security, protesters clashed with police at nearly half-a-dozen places in Srinagar and also in the town of Baramulla, about 55 kilometres north of Srinagar, police said. In the latest attacks by suspected freedom fighters a scooter mechanic and a policeman were killed and eight other people wounded in separate grenade and gun attacks on Monday in the northern town of Sopore, a police spokesman said. The injured included five employees of the federal telecommunication department, a civilian and two policemen, he said. Tensions have been running high for months after local police accused the military of killing three civilians in April. The occupation authorities had placed Mirwaiz Umar Farooq and several other Hurriyat leaders under house arrest. Indian police had arrested Syed Ali Geelani along with Muhammad Ashraf Sehrai, after they addressed a public gathering at Silkote in Kupwara. Syed Ali Geelani was detained at Humhama Police Station while Ashraf Sehrai at Srinagar Central jail.
