Israeli Prime Minister Benjamin Netanyahu has said that he is prepared to release 1,000 Palestinian prisoners in exchange for a captured Israeli soldier as long as certain conditions are met.In a live address on television, Mr. Netanyahu said Israel is ready to pay a heavy price to free Shalit, but not any price. Netanyahu said the prisoners could go to Tunisia or the Gaza Strip but not to locations where they could continue to harm Israelis. He said his second condition is that the most dangerous prisoners would not be freed.The prime minister’s comments have come when pressure is mounting on his government after the family of Israeli soldier Gilad Shalit marked the fourth year of his captivity. Shalit's family began a 12-day walk to Jerusalem last week demanding steps to free him. Hamas captured Shalit near the Gaza border in 2006.Hamas spokesman Ismail Radwan has dismissed the prime minister's speech terming it ‘nothing new’.
