A top army officer says the seven men, carrying machine guns and ammunition, were killed in an early morning encounter in the border district of Punjab, northwest of Jammu. He says the army ambushed the men after receiving information about the infiltration attempt. He said all seven belonged to the Pakistan-based Al-Badr guerrilla outfit.
