Hamas and Hizbullah have signed a cooperation accord. The leaders of Hamas and Hizbullah met on April 1 in Beirut and signed a statement declaring their war against Israel as legitimate. The meeting of Hizbullah secretary-general Hassan Nasrallah and Hamas political chief Khaled Mashaal ended with a joint call against disarming their groups. For its part, Hamas said the reduction in the Palestinian insurgency campaign in the West Bank and Gaza Strip depended on the halt of Israeli attacks and the release of all Palestinian prisoners. "Hamas will not be committed to remain calm if Israel fails to meet its demands," Hamas said in the statement.
