Israeli strikes hit a crowded shopping area in Gaza City Wednesday, hours after tank shells tore through the walls of a UN school crowded with war refugees in the deadliest of a series of air and artillery attacks that pushed the Palestinian death toll above 1,360 in more than three weeks of fighting.
The bloodshed came on the heels of an escalation by both sides fighting in the embattled coastal territory, further dimming prospects for a sustainable ceasefire despite international diplomatic efforts.
The attack on the UN school in the Jebaliya refugee camp was the second deadly strike on a UN compound in a week. Tank shells slammed into the compound before dawn, said Adnan Abu Hasna, a spokesman for the UN Relief and Works Agency (UNRWA), which is sheltering more than 200,000 people displaced by the fighting at dozens of UN schools across Gaza.

Gaza health ministry official Ashraf al-Kidra said at least 17 people were killed and about 90 wounded in the school strike. Four of the dead were killed just outside the school compound, two in their home nearby and two in the street, after returning from pre-dawn prayers, their relatives said.
Assad Sabah said he and his five children were huddling under desks in one of the classrooms because of the constant sound of tank fire throughout the night.
"We were scared to death," he said. "After 4:30 a.m., tanks started firing more. Three explosions shook the school."
"One classroom collapsed over the head of the people who were inside," he said.
In one classroom, the front wall was blown out, leaving debris and bloodied clothing. Another strike tore a large round hole in the ceiling of a second-floor classroom.
Hundreds of people crowded the school courtyard after the strike, some dazed, others wailing.
"Where will we go?" asked Aishe Abu Darabeh, 56. "Where will we go next? We fled and they (the Israelis) are following us."
In all, 1,361 Palestinians have been killed — 116 on Wednesday — and 7,600 wounded since the July 8 start of fighting, al-Kidra said.
3 Israeli soldiers killed Wednesday
The UN said it was the sixth school to be hit since the conflict began, and the second to cause deaths. At least 15 civilians also were killed last Thursday when the courtyard of a UN school in Gaza City was hit. Israel has acknowledged that troops fired a mortar shell that hit the courtyard but said aerial footage shows the yard was empty at the time and that the shell could not have killed anyone.
Nothing is more shameful than attacking sleeping children.- Ban Ki-moon, UN Secretary-General
"I reached levels of anger and indignation about the fact that despite all the efforts that we have put in, to ensure that places like these would be respected, that people in them would be protected when they were there — that this was not the case is intolerable," said Pierre Kraehenbuehl, the UNRWA commissioner general.
Secretary-General Ban Ki-moon called Wednesday's strike "outrageous" and "unjustifiable," and demanded an immediate humanitarian ceasefire in the war between Israel and Hamas.
"Nothing is more shameful than attacking sleeping children," Ban said on his arrival in San Jose, Costa Rica. He added that "all available evidence points to Israeli artillery as the cause" and noted that Israeli military authorities had received the co-ordinates of the school from the United Nations 17 times, including on Tuesday night.
The White House also condemned the deadly shelling. White House spokeswoman Bernadette Meehan also said the U.S. is "extremely concerned" that thousands of Palestinians aren't safe in U.N.-designated shelters, despite being told by Israel's military to leave their homes. Israel has been warning civilians by phone and leaflet to leave dangerous areas ahead of strikes on militant targets.
Yomtov Tamir, a retired Israeli general, said he was not familiar with Wednesday's strike but said that even though tank fire is generally "very accurate" it can miss its target for a variety of reasons.
"One — it might have gone through a target. Two — it might be a mistake in identification, that they intended to hit something specific but that it was actually something other than what the person aiming intended," he said.
Hours later, an Israeli airstrike hit a crowded shopping area in the Shijaiyah district in Gaza City, killing at least 16 people, including local Palestinian photographer Rami Rayan, who was wearing a press vest at the time, and wounding more than 200 people, Gaza health officials said.
Al-Kidra and witnesses said the shopping area was busy because residents, and many who had taken shelter in the area from fighting elsewhere, thought a cease-fire was in place. The Palestinian Red Crescent confirmed the death toll.
The Israeli military had no immediate comment on the strike on the shopping area, saying it was investigating the report.
Canadian government stands behind Israel
In Saskatchewan, Harper says that while no one likes to see the suffering and loss that is occurring in the Middle East, Hamas is to blame.
The prime minister calls Hamas a terrorist organization that has initiated the conflict, and continues it because it seeks the destruction of the state of Israel.
Meanwhile, a Canadian delegation of MPs and senators visited Ashkelon, near the border of Gaza, to meet with local officials.
Some of the Canadian politicians are on a fact-finding mission, the CBC's Nahlah Ayed said, while "others are here to show their support for Israel and its fight against Hamas."
Ceasefire lacked 'value': Hamas
The Israeli military had declared a four-hour humanitarian ceasefire in parts of Gaza beginning at 3:00 p.m., but Hamas spokesman Sami Abu Zuhri said it lacked any "value" because it excluded border areas from where Hamas wanted to evacuate the wounded.
Gaza militants fired 84 rockets at Israel Wednesday, including more than 26 after the ceasefire was announced, the military said. Al-Kidra, the Gaza health official, said seven Palestinians were killed by an Israeli airstrike in the same period.
The latest violence further dimmed hopes of a sustainable truce in the fighting, now in its fourth week.
