A British surgeon working in southern Gaza has compared the region to a "slaughterhouse" because of the daily bombardment from Israeli forces.

Dr Tom Potokar offered his assessment of the military offensive after Palestinian health officials reported at least 130 people were killed overnight into Sunday.

Israel Defence Forces (IDF) confirmed troops had begun "extensive ground operations throughout the northern and southern Gaza Strip".

In a video, Dr Potokar said it was "another day of devastation here in Gaza", adding: "The stories coming from the north... absolutely horrific... particularly around the Indonesian Hospital.

"I mean, it's difficult to describe in words what's happening here... [with the] constant sound of bombardment jets overhead.

"If Cambodia was the killing fields, then Gaza now is the slaughterhouse."

His reference to Cambodia's killing fields refers to when more than a million people were murdered in mass executions and buried by the extreme communist guerrilla group, the Khmer Rouge, under Pol Pot, between 1975 and 1979.

The Hamas-run health ministry in Gaza said 464 people had died in Israeli military strikes in the week to Sunday.

In a statement on Sunday, IDF said its air force struck "over 670 Hamas terror targets throughout the Gaza Strip to disrupt enemy preparations and support ground operations" over the past week.

Dr Potokar described the impact on those on the ground, saying: "We've been operating all morning so far and [treating] awful explosive injuries... [including] one young woman with leg fracture and shoulder fracture and a large wound on her buttock, who came in yesterday and is not yet aware that everyone in our family was killed in the onslaught."

Israel has launched an escalation to increase pressure on Hamas, seize territory, displace Palestinians to the south and take greater control over the distribution of aid.

On Sunday, it announced and launched "extensive" new ground operations in Gaza.

It came after airstrikes killed at least 130 people, including dozens of children, overnight and into Sunday, hospitals and medics said, and forced northern Gaza's main hospital to close.

A spokesperson for the Hamas-run health ministry said: "Complete families were wiped off the civil registration record by Israeli bombardment."

The ministry also said the attacks had forced the closure of the Indonesian Hospital, the main hospital serving people in northern Gaza.

Nasser hospital, in the southern city of Khan Younis, said more than 48 people - mostly women and children - were killed in the area which includes tents sheltering displaced people.

In Deir al Balah, in central Gaza, at least 12 people were killed in three separate strikes, according to Al Aqsa Martyrs Hospital and the Nuseirat camp's Awda Hospital.

Meanwhile, the Gaza health ministry and the Palestinian Civil Defence - which operates under the Hamas-run government - reported that 19 people were killed in several strikes in Jabalia in northern Gaza.

The Israeli military had no immediate comment on the strikes.

How Israel has escalated Gaza bombing campaign

Ceasefire talks are taking place in Qatar this weekend - with Israel saying they involve discussions on ending the war as well as a truce and hostage deal.

A statement from the office of Israeli Prime Minister Benjamin Netanyahu said any lasting truce must include the demilitarisation of Gaza as well as the exile of Hamas militants.

But a senior Israeli official added there had been little progress so far during talks in Qatar's capital Doha.

Sky News Arabia reported Hamas had proposed freeing about half its Israeli hostages in exchange for a two-month ceasefire and the release of Palestinian prisoners held by Israel.

A Palestinian official close to the discussions said: "Hamas is flexible about the number of hostages it can free, but the problem has always been over Israel's commitment to end the war."
