NEW DELHI, India (AP) _ Sikh militants fired a rocket at a base of the paramilitary Central Reserve Police Force and killed one policeman, the Press Trust of India news agency said today.

Five policemen were injured in the attack Wednesday night on the post near Amritsar in Punjab state, the news agency said.

It was the fifth time this year the militants have fired a rocket. Previous targets were a police jeep, a Central Reserve Police barracks, a police patrol party and the house of a moderate Sikh leader.

Elsewhere in Punjab on Wednesday, Sikh militants killed two people, both Sikhs, officials said.

The killings raised to 1,270 the number of deaths in Punjab this year from the Sikh militants' violent agitation for an independent homeland.

The victims have included at least 542 Sikhs who the militants claimed were police informers.

Sikhs form only 2 percent of India's 800 million people but are in a majority in Punjab. Dissident Sikhs launched a campaign for an independent homeland in Punjab in 1982, claiming discrimination by Hindus, who comprise 80 percent of the national population.
