Gaza Strip, May 30: Israeli shelling and airstrikes killed at least 37 people, most of them sheltering in tents, outside the southern Gaza city of Rafah overnight and on Tuesday — pummelling the same area where strikes triggered a deadly fire days earlier in a camp for displaced Palestinians — according to witnesses, emergency workers and hospital officials.

The tent camp inferno has drawn widespread international outrage, including from some of Israel’s closest allies, over the military’s expanding offensive into Rafah. And in a sign of Israel’s growing isolation on the world stage, Spain, Norway and Ireland formally recognized a Palestinian state on Tuesday.

The Israeli military suggested Sunday’s blaze in the tent camp may have been caused by secondary explosions, possibly from Palestinian militants’ weapons. The results of Israel’s initial probe into the fire were issued Tuesday, with military spokesman Rear Adm. Daniel Hagari saying the cause of the fire was still under investigation but that the Israeli munitions used — targeting what the army said was a position with two senior Hamas militants — were too small to be the source.

The strike or the subsequent fire could also have ignited fuel, cooking gas canisters or other materials in the camp. The blaze killed 45 Palestinians, according to Gaza health officials’ count. Israeli Prime Minister Benjamin Netanyahu said the fire was the result of a “tragic mishap.”

Israel’s assault on Rafah, launched May 6, spurred more than 1 million people to flee the city, the U.N. agency helping Palestinian refugees said Tuesday. Most were already displaced multiple times in the nearly eight-month war between Israel and Hamas. Families are now scattered across makeshift tent camps and other war-ravaged areas. The strikes over the past few days have hit areas west of Rafah, where the military had not ordered civilians to evacuate. Israeli ground troops and tanks have been operating in eastern Rafah, in central parts of the city, and along the Gaza-Egypt border.

Shelling late Monday and early Tuesday hit Rafah’s western Tel al-Sultan district, killing at least 16 people, the Palestinian Civil Defense and the Palestinian Red Crescent said. Seven of the dead were in tents next to a U.N. facility about about 200 metres (yards) from the site of Sunday’s fire.

“It was a night of horror,” said Abdel-Rahman Abu Ismail, a Palestinian from Gaza City who has been sheltering in Tel al-Sultan since December. He said he heard “constant sounds” of explosions overnight and into Tuesday, with fighter jets and drones flying above. (AP)
