Here are 10 developments in the story:
Home Minister Rajnath Singh, Foreign Minister Sushma Swaraj and Defence Minister Manohar Parrikar met to discuss the situation at the border.
Pakistan summoned the Indian envoy this morning and lodged a protest after saying it had shot down an Indian "spy" drone, a claim that has been denied by New Delhi.
Pakistan Foreign Secretary Aijaz Ahmed Chaudhary protested against "cross-border firing by India" and also claimed that an Indian spy plane had been shot down for violation of "Pakistan's territorial integrity."
Indian High Commissioner TCA Raghavan denied that the drone was Indian, and asserted that it was Pakistan that fired first at the border.
The Pakistan army alleges that India was using the drone for aerial photography near the Line of Control and it was shot down in the Bhimber area of Pakistan Occupied Kashmir for "violation of Pakistan's territorial integrity."
The claim has been questioned because the drone does not appear to be of the kind used by India. Indian officials say the drone is used for highway patrolling, and could have belonged to the police of Pakistan's Punjab province.
Indian government sources called it a "strange coincidence that Pakistan claimed it shot down an Indian drone soon after the violation" on Wednesday.
A woman was killed and six, including two soldiers, were injured in heavy firing from across the border in Jammu's Akhnoor sector. In more firing this morning in Jammu, three villagers have been injured at the RS Pura sector.
The ceasefire violations come just ahead of Prime Minister Narendra Modi's visit to Jammu on Friday.
Last week, PM Modi and his Pakistani counterpart Nawaz Sharif held talks on the sidelines of a regional conference in Ufa in Russia. As part of breakthrough announcements after the talks, the two countries decided to arrange meetings of senior military officials to reduce tension along the border.
