The Indian Army killed three infiltrating militants in two separate encounters on the Line of Control in north Kashmir Kupwara border district on Thursday.

A defence spokesman in Srinagar [Images] said two heavily armed groups of infiltrating militants were challenged by the army in the Machil and Keran sectors of the LOC in Kupwara district Thursday morning.

"So far, two infiltrators have been killed in the Machil sector while one was killed in the Keran sector. The operation is still on," Col. Manjinder Singh, spokesman of 15 Corps told rediff.com.

A senior police officer here said infiltration attempts are sped up by the militants each year around autumn before the closure of the mountain passes due to the heavy snowfall along the LOC.
