Blast Kills 5 Palestinians in Car, but Israeli Army Denies Role
The car carrying the men was hit by an explosion as it traveled on a back road between Rafah and Khan Yunis, not far from a crossing between the Gaza Strip and Israel.

Palestinian security officers and people at the scene said that the car had been hit by a missile, and that two Israeli helicopters and a drone were hovering at the time of the explosion.

"This means it does not want calm," Mr. Arafat said, referring to Israel. "It wants the continuation of the military escalation against our mighty people."

The Democratic Front for the Liberation of Palestine, a Marxist faction in the Palestine Liberation Organization, said the Palestinians belonged to its group, and it vowed revenge.
