Srinagar , India ( CNN ) -- The Indian army accused Pakistani troops of violating a cease-fire agreement early Thursday by firing across the Line of Control that divides Kashmir . Pakistani border troops fired for about 90 minutes in Poonch district of the Indian state of Jammu and Kashmir , said Biplab Nath , an Indian army spokesman . The Pakistanis used heavy volumes of small arms , and heavy caliber weapons such as mortars and rocket propelled grenades , Nath said . Indian troops retaliated `` appropriately '' to the `` unprovoked '' firing , he said . A spokesman for the Pakistani military confirmed the gunfire , but said Indian troops fired at their soldiers . Spokesman Maj. Gen. Athar Abbas said the two nations have agreed to meet soon to discuss the incident and seek clarification . Nath said there were no casualties on the Indian side . `` Our assessment is that this firing was to primarily assist infiltration of terrorists , '' he said . Such ceasefire violations have been common since 2003 , but Nath described the latest incident firing as `` major . '' Kashmir has been a source of bitter dispute between India and Pakistan since the independence of both nations in 1947 . Under terms agreed by the two countries , Kashmir 's rulers could either opt to merge with India or Pakistan or remain independent . One part sided with Pakistan . The ruler of the other part sided with predominantly Hindu India , sparking a controversy among the region 's Muslim majority . India and Pakistan have fought three wars over Kashmir and militants , who India says are backed by Pakistan , have been fighting since the late 1980s to end Indian rule in the region . A cease-fire to end the violence was agreed to in 2003 . Both India and Pakistan routinely accuse each other of firing across the border . CNN 's Samson Desta contributed to this report .
