The Hamas terrorist organization in Gaza has accused the terrorists who fired a Kassam rocket attack at the western Negev city of Sderot on Monday of being collaborators with Israel.

Senior Hamas official Mahmoud al-Zahar told reporters in Gaza on Tuesday,"I believe that those who fired the rocket at Israel are collaborators with Israel in order to increase the pressure on Hamas movement and on the Palestinian people."

 No one claimed responsibility for the attack, the 40th such violation of the temporary truce that went into effect on June 19. No one was injured.
