Pakistani troops opened fire and pounded Indian posts and civilian areas along the Jammu frontier with mortar shells overnight, the Times of India reports.
Soldiers attacked up to 25 Border Security Force (BSF) posts along the international border in the Samba district of Jammu and Kashmir on Friday night.
NDTV calls it the biggest ceasefire violation in 10 years.
Border guards on both sides of the border near Kashmir exchanged heavy fire and mortars at numerous locations, according to Xinhua.
Meanwhile, AFP reports that Pakistan has accused Indian troops of killing a civilian and wounding two others in "unprovoked firing" across the border.
Jammu and Kashmir chief minister Omar Abdullah had requested the Indian government to take up the ceasefire violation issue with Pakistan.
"It is not clear who is behind this and with what motive this is being done. Some days back our Prime Minister met the Pakistani PM in New York. They talked about ceasefire violations and it was decided that the armies of both countries should talk and find a way out," he had said.
Over 130 ceasefire violations have been reported in 2013, the highest in the past 8 years.
