Indian Prime Minister Manmohan Singh has expressed his disappointment with his Pakistani counterpart Nawaz Sharif for failing to keep his promise to stop ceasefire violations in Kashmir, said local media Friday. \"I am disappointed, because in the New York meeting (with Sharif) there was a general agreement on both sides that peace and tranquility should be maintained on the border, on the Line of Control as well as on the international border and this has not happened,\" Singh was quoted as saying on Thursday onboard his plane while returning home from visits to Russia and China. \"It has come to me as a big disappointment. We had agreed at that meeting that the ceasefire which was made effective in 2003, if it has held for 10 years, it could be made to hold ground later also,\" he said. India has said that Pakistan violated at least 200 times so far this year a 2003 ceasefire along the Line-of-Control and international border in Kashmir and that there has been a sharp rise of such violations recently. One Indian border guard was killed and three injured by Pakistan shelling this week. Pakistan has rejected the accusation.
