An explosion killed at least five members of Ezzedine al-Qassam Brigades, the military wing of Hamas, in a tunnel under the Israeli border, Thursday, according to Palestinian Authority officials cited by Agence France Presse. A security source told AFP the "accidental explosion" happened "inside of an Al-Qassam Brigades tunnel, which collapsed on some 12 members." Eyewitnesses reported a large explosion near the border with Israel.
Following initial denials, the local Hamas information office said, without elaborating, "Five martyrs were killed in a resistance activity in the Saghira
neighborhood" in eastern Gaza City. The Israeli army told AFP it had no knowledge of the incident.
