Israel has confirmed responsibility after a deadly explosion “like an earthquake” reportedly killed about 50 people in Gaza’s largest refugee camp.

Photos reveal a huge crater and flattened buildings in the Jabalia camp – a community of crammed and narrow streets that is usually home to 116,000 people.

The Israel Defence Force on Wednesday morning (AEDT) confirmed its fighter jets had attacked the camp in northern Gaza and killed senior Hamas commander Ibrahim Biari.

The deadly strike also caused the collapse of Hamas’s underground infrastructure.

IDF spokesperson Daniel Hagari said the buildings targeted were used extensively by Hamas to launch “terrorist activities” against Israel.

The BBC reports that journalists at the scene counted at least 47 bodies, with pictures showing dead or seriously injured children.

Israeli armed forces dropped more bombs on Gaza overnight Tuesday (AEDT) in air, sea and ground attacks, targeting north-western areas of the Palestinian enclave.

Israel’s forces have also targeted the Hamas militant group’s vast tunnel network beneath Gaza.

The tunnels are a key objective for Israel as it expands ground operations inside Gaza to wipe out the ruling Islamist Hamas movement following its surprise attack three weeks ago.

Israel shows attack video

A group of Australian journalists were shown a compilation of videos of Hamas’s October 7 attack.

The footage included videos filmed by Hamas, which is classified as a terrorist organisation by the Australian government, as well as CCTV vision, videos taken by terrified victims and first responders.

Babies and small children were murdered, with their bodies burnt by the militants.

Piles of bodies of butchered Israelis were found in their homes, as blood streaked the floor and walls.

The video showed the bodies of gunned-down festival goers, including a woman found with her skirt hiked up around her waist and her underwear pulled down.

The Australia Palestine Advocacy Network labelled the screening a “desperate bid” to stem international criticism of its response in Gaza.

The group’s president Nasser Mashni said one atrocity did not justify another.

“Hamas’ actions occurred on one black day,” he said.

“Israel has been perpetrating that horror on the people of Gaza for 24 black days now and for over 27,000 days before October 7.”

“It is time people of good conscience in Australia demand that all life be equally valued, that all babies, women and men are precious,” he said.

At least 1400 Israelis were killed by Hamas and more than 230 were taken hostage.

Gaza health authorities say 8306 people, including 3457 minors, have been killed in Israeli attacks since October 7.

UN officials say more than 1.4 million of Gaza’s civilian population of about 2.3 million have been made homeless.

The mounting death toll has drawn calls from the US, Israel’s top ally, other countries and the UN for a pause in fighting to allow more humanitarian aid to reach the enclave.

Netanyahu said Israel would not agree to a cessation of hostilities and would press ahead with its plans to wipe out Hamas.

“Calls for a ceasefire are calls for Israel to surrender to Hamas, to surrender to terrorism, to surrender to barbarism. That will not happen,” Netanyahu said in televised remarks.

Aid trucks have been trickling into Gaza from Egypt over the past week via Rafah, the main crossing that does not border Israel. It has become the main point of aid delivery since Israel imposed a “total siege” of Gaza after October 7.
