( CNN ) -- Three Pakistani paramilitary soldiers were killed this week in a cross-border firefight between Pakistan and India , officials said Thursday . The soldiers were moving from one post to another along the border when they came under fire by Indian forces , said Maj. Gen. Athar Abbas , Pakistan army spokesman . Since a cease-fire is in effect , the firing by Indian forces was unprovoked , Abbas said . But Pakistani forces retaliated after the shots were fired , he said . It was unclear whether the incident took place late Tuesday or Wednesday , as Pakistani and Indian officials provided different times . Lt. Col. J.S . Brar , Indian defense spokesman for the disputed Kashmir region , said there were two violations of the cease-fire on the Line of Control , the de facto border between Indian- and Pakistan-administered Kashmir . In the first , fighting continued for about an hour , he said . A second violation took place Thursday morning , he said , and one Indian soldier was injured . Brar said he could not comment on Pakistani casualties . Pakistani officials said severe weather conditions in Kashmir , a Himalayan region , hampered removal of the soldiers ' bodies . Pakistan has asked the Indian local commanding authority for a full report on the incident . India and Pakistan have have fought three wars since the partition of the Asian subcontinent in 1947 . Two of them were over Kashmir , which is claimed by both nuclear powers . On August 20 , an Indian army officer and five militants were killed in clashes along the Line of Control .
