(CNN) -- The Indian army accused Pakistani troops of violating a major cease-fire early Thursday by firing across the line of control in Kashmir. Pakistani border troops fired for about 90 minutes in Poonch district of Jammu Kashmir, said Biplab Nath, a spokesman for the Indian army in Jammu. They used heavy volumes of small arms and heavy caliber weapons, such as mortars and rocket-propelled grenades, the spokesman said. Indian troops retaliated "appropriately" to the "unprovoked" firing, Nath said. A spokesman for the Pakistani military said he was looking into the report and would comment when he had more information. Nath said there were no casualties on the Indian side, and they were seeking a meeting with Pakistan. "Our assessment is that this firing was to primarily assist infiltration of terrorists," he said. Such cease-fire 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. 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 India, where most people are Hindu, sparking a controversy among the region's Muslim majority. The line of control was formally established in 1972. There have been routine accusations that both sides fire across the line -- which they have denied. http://edition.cnn.com/2010/WORLD/asiapcf/08/19/india.pakistan.fire/#fbid=kqcmObrH9HR&wom=false even at this time of floods why is it breaching cease fire again!!!!!!!!!!
