( CNN ) -- Pakistan and India exchanged fire near the border in the disputed Kashmir region early Saturday , killing at least two people from each country . The Indian paramilitary border security force said Pakistani forces fired shots and mortar rounds near the border , killing a father and his 8-year-old son , and injuring four others , including a trooper . A spokesman for the security force called the action from the Pakistani side `` unprovoked . '' The Pakistani military said an intermittent exchange of fire continues between the countries . It accused Indian troops of `` unprovoked '' opening fire on the working boundary near Sialkot , killing two civilians -- a woman and a 60-year-old man . The two nuclear-armed countries agreed to a bilateral ceasefire in November 2003 . But while it has held well , it has suffered breaches since last year . The latest round of violence has triggered the dislocation of more than 1,000 border residents , an Indian official said . Kashmir has been in the throes of separatist violence since 1989 ; officials say it has claimed 42,000 lives , but rights groups and nongovernmental organizations put the number at twice that . Talks called off . The latest bloodshed comes amid recent diplomatic tensions . India called off talks planned for Monday with Islamabad after Pakistan 's New Delhi-based high commissioner , Abdul Basit , invited Kashmiri separatist leaders for consultations ahead of the summit . The New Delhi foreign secretary told Basit `` in clear and unambiguous terms , that Pakistan 's continued efforts to interfere in India 's internal affairs were unacceptable , '' India 's External Affairs Ministry said in a statement . `` The meetings with these so-called leaders of the Hurriyat undermines the constructive diplomatic engagement initiated by Prime Minister ( Narendra ) Modi in May on his very first day in office , '' the ministry said . But Pakistan said in a statement it is a `` longstanding practice '' to meet with Kashmiri leaders before India-Pakistani talks are held . `` The Indian decision is a setback to the efforts by our leadership to promote good neighborly relations with India . The prime minister of Pakistan has clearly articulated the vision of peace for development , '' the statement said . `` It seems a knee-jerk reaction , '' said Mirwaiz Moulvi Umar Farooq , a moderate Kashmiri separatist leader . `` We have been meeting the Pakistani officials , including the country 's New Delhi-based high commissioner , for the past 20 years . I do n't know what happened today . It is a backward step . '' He said the move is short-sighted . `` The decision lacks political maturity and can not be termed as far-sighted , '' he said . 'Not a good development ' Hardline separatist leader Syed Ali Shah Geelani described the decision as unfortunate , saying it proved that `` New Delhi was never serious to resolve Kashmir peacefully . '' Even mainstream political parties have expressed dismay at the cancellation of the talks . `` It is not a good development . The separatists have been meeting Pakistani officials . They even met the then-Pakistan president , Pervez Musharraf , '' said Ali Mohammad Sagar , a senior ruling National Conference leader and minister . During his visit to Indian-administered Kashmir this month , Modi condemned `` the continued proxy war by neighboring Pakistan . '' Addressing army officers and soldiers in the frontier Ladakh region bordering China and Pakistan , Modi said that `` the neighboring country has lost the strength to fight a conventional war but continues to engage in the proxy war of terrorism . '' Modi 's criticism of Islamabad came against in the backdrop of reported ceasefire violations by Pakistani troops on the border and increased militant attacks in Kashmir . CNN 's Sophia Saifi reported from Islamabad and Journalist Mukhtar Ahmad reported from Srinagar . CNN 's Harmeet Shah Singh contributed to this report .
