A pickup truck carrying masked terrorists blew up at a Hamas rally at the Jebaliya refugee camp in the Gaza Strip on Friday. At least least 19 Palestinians were killed and 85 injured, hospital doctors said.

Channel Two reported that while conflicting reports were received, the truck appeared to have been carrying a number of missiles, one of which exploded due to mishanding.

Hamas blamed Israel, saying Israeli aircraft flew overhead during the rally.

Defense Minister Shaul Mofaz denied that Israel had any involvement in the explosion. However, Mofaz, in messages conveyed to Palestinian Authority officials, declared that Israel holds the PA responsible for the situation and expects it to ensure that calm prevails.

Initial reports indicated that Ahmed Randoul, a key figure in Hamas, was either killed or seriously injured in the explosion. Israeli security forces have neither confirmed nor denied this.

Ten of the injured were in serious condition, hospital doctors said.

Witnesses said participants crowded around the pickup truck carrying terrorists when the explosion went off...
