Pakistan has complained to the UN Security Council (UNSC) about India's plans to construct a wall along the Line of Control allegedly to convert it "into a quasi-international border".Pakistan's ambassador to the UN Maleeha Lodhi has written two letters dated September 4 and 9 to the UNSC.In the September 9 letter to UNSC President Vitaly Churkin, Lodhi expressed "deep concern" at the plan by India to construct a 10-metre-high and 135-feet-wide embankment (wall) along the 197km boundary between Jammu & Kashmir and Pakistan.In the letter, Lodhi said Pakistan "considers the embankment a permanent structure that will bring about a material change in the territory in violation inter alia of Security Council resolution of 1948."The state of Jammu & Kashmir is internationally recognised disputed territory with a number of United Nations security council resolutions on the official status of Jammu & Kashmir awaiting implementation," Lodhi said.Meanwhile, the Indian Ministry of External Affairs spokesperson Vikas Swarup told reporters on Thursday that India was aware of the two letters that had been written.The first letter written on September 4 says there is no bilateral dialogue, Swarup said, adding the BSF and Pakistan Rangers have already met."So the letter itself has contradicted itself that there is no dialogue. There has been a dialogue," Swarup said.
