Mahmoud Abbas told Hamas that it has 10 days to accept a two-state solution to the Israeli-Palestinian conflict or accept a Palestinian referendum on a two-state plan. Speaking Thursday in the West Bank, the Palestinian Authority president said he would seek to hold the referendum within 40 days. Hamas officials were quoted as saying they back the idea of a referendum. The vote would be based on a plan drafted earlier this month by Palestinians jailed in Israel. It calls for a Palestinian state in the West Bank, Gaza and eastern Jerusalem, the areas Israel captured in the 1967 Six-Day War. Islamic Jihad said it opposes the referendum.
