RAFAH, Gaza Strip (AP) -- The first of August dawned as a day of promise for the Mahmoum clan and thousands of other Palestinians stuck in United Nations shelters in Rafah -- thanks to a temporary cease-fire with Israel they could go home for three days.
But the expected respite quickly turned into one of the deadliest and most controversial episodes in the recent war between Israel and Hamas in the Gaza Strip. After just two hours, amid fear that Hamas had captured an Israeli soldier, the Israeli military sealed off the Rafah area and began shelling. By the end of the next day, 190 Palestinians were dead, according to a list of names compiled by two Gaza human rights groups, including 14 members of the Mahmoum family.
The Rafah operation is almost certain to be a focus of U.N. investigators and rights groups looking into possible war crimes because it highlights a key concern: The treatment of civilians.
A Palestinian rights group argues that the Israeli army violated the rules of war, which include giving adequate warning to civilians, using proportionate force and distinguishing between civilians and combatants. Unlike in many other Gaza battles, civilians were caught by surprise by the sudden fire and sealed exits.
"None of the rules of international humanitarian law was observed," said Mahmoud Abu Rahma of the Al Mezan rights group.
The Israeli military confirmed that Rafah residents were barred from leaving the area on Aug. 1, but declined comment on the war crime allegations. It denied firing into a densely populated area without regard for civilians, saying precise airstrikes hit targets linked to militants and artillery -- though inherently inaccurate -- was only aimed at open fields.
Late on Aug. 2, the suspected capture of the soldier turned out to be a false alarm, and the Rafah episode is one of several under internal military review.
"If we accidentally or mistakenly targeted a civilian situation, it was a mistake, and we are very sorry about that," an officer from the army's Southern Command said on condition of anonymity as he wasn't authorized to speak on the record.
The following account is from interviews with Palestinian survivors and the Israeli military, along with events witnessed by The Associated Press.
The cease-fire took effect at 8 a.m. Friday. Mustafa Mahmoum, a municipal bulldozer operator, was at work clearing rubble from previous Israeli strikes. But after weeks in a shelter, his wife Iqzayer, 34, and their seven children returned to the family home in Tannour in east Rafah, about 2 miles (3 kilometers) from the Israeli border.
A few houses down Ouroba Street, the main thoroughfare, Azizeh, 47, the wife of one of Mustafa's cousins, and her nine children also moved back home into their two-room shack with a roof of corrugated metal.
At 9 a.m., the commander of Israel's Givati Brigade, Col. Ofer Winter, had just dozed off after a sleepless night when he received an alert from the field.
Givati soldiers searching for Hamas' network of military tunnels had been ambushed by Hamas gunmen, he was told. Over the next half hour, it became apparent that Maj. Benaya Sarel, a recon officer, and Liel Gidoni, his radio operator, had been killed, and 2nd Lt. Hadar Goldin was missing.
At 9:36 a.m., Winter announced over the field radio the word nobody wanted to hear: "Hannibal."
Hannibal is the name for the military protocol to be followed if a soldier falls into enemy hands. The aim is to stop the capture, even if it means loosening open-fire regulations.
Winter ordered all forces to take territory so that the kidnappers couldn't move, he told Israel's Yediot Ahronot newspaper.
The officer in the Southern Command, which oversaw the Gaza fighting, told the AP the brigade tried to seal off an area with a radius of 2-3 kilometers (1.5 miles) around the suspected capture point, a mile from the border. Over the next eight hours, soldiers fired about 500 artillery shells, he said. The military said it also launched about 100 airstrikes against targets in Rafah on Aug. 1 and 2, but did not provide a breakdown for each day.
The priority was to rescue Goldin.
"That's why we used all this force," Winter told the newspaper. "Those who kidnap need to know they will pay a price. This was not revenge. They simply messed with the wrong brigade."
The assault began sometime before 10 a.m., sending Azizeh Mahmoum and her children fleeing from their shack to Mustafa's sturdier brick home. Within minutes relatives gathered. As the fire became more intense, they no longer felt safe. So they ran across Ouroba Street in groups, trying to reach a small, narrow alley for cover. The alley lay next to a supermarket owned by the Bilbesis, a relatively wealthy family, and led toward a hospital.
