About 7,000 Hamas supporters have held a rally in Gaza City to mark the anniversary of the assassination of the group's founder and send a warning to Israel.
Hamas spiritual leader Sheikh Ahmed Yassin was killed in an Israeli air strike March 22, last year.
Hamas leaders Friday vowed to resume attacks on Israel unless it accepts their demands for prisoner releases and other concessions. A top Hamas official said he would participate in cease-fire talks scheduled next week in Egypt, but has not decided on whether the group will sign an agreement.
Some palestinian militants have been observing a "cooling off" period with Israel that was agreed to during a recent summit in Sharm el-Sheik, Egypt.
