Israeli troops have killed 12 Palestinians and wounded 40 in Gaza City and another 10 Palestinians were wounded in Rafah in one of the bloodiest days in the Occupied Territories in months. There were no reports of Israeli casualties. Hamas has vowed large suicide attacks in retaliation. Palestinian negotiations minister Saeb Erakat said “”We strongly condemn this aggression, this massacre while efforts are being made to revive the peace process.” Israeli officials said it invaded Gaza City with tanks early this morning after an army post came under mortar attack.
