Israel has carried out air strikes in Gaza, in response to what Israeli officials said were violations of the US-brokered ceasefire agreement.

Defence Minister Israel Katz accused Hamas of attacking Israeli soldiers in Gaza on Tuesday, and breaching the terms on returning the bodies of deceased hostages.

The Palestinian armed group claimed it had 'no connection' to the attack and insisted it was committed to the ceasefire deal.

First responders in Gaza said at least nine Palestinians were killed in a wave of Israeli strikes across the territory on Tuesday evening.

Despite the flare-up, US Vice-President JD Vance said he believed the ceasefire was holding.

A brief statement put out by Prime Minister Netanyahu's office on Tuesday evening said he had ordered 'forceful strikes' by the military but did not specify his reasons.

However, Defence Minister Katz said Hamas had crossed 'a bright red line' by launching an attack on Israeli soldiers in Gaza on Tuesday.

Hamas will pay many times over for attacking the soldiers and for violating the agreement to return the fallen hostages, he warned.

An Israeli military official stated the attack took place 'east of the Yellow Line', which demarcates Israeli-controlled territory inside Gaza under the ceasefire deal.

Israeli media reported that troops in the southern Gaza city of Rafah had come under sniper fire while Palestinian media reported Israeli artillery shelling there. Subsequently, witnesses noted significant explosions in several parts of Gaza, including the northern Gaza City and southern Khan Younis.

A spokesman for the Hamas-run Civil Defence agency reported that at least four people were killed, including three women, when an Israeli strike hit a home in Gaza City's Sabra neighborhood.

Strikes also reportedly impacted the courtyard of al-Shifa hospital in the western Rimal district.

Hamas denied the allegations of attacking Israeli troops, describing the Israeli strikes as a blatant violation of the ceasefire agreement.

The ceasefire agreement, brokered by the US, Egypt, Qatar, and Turkey, is supposed to implement the first stage of President Donald Trump's 20-point Gaza peace plan aimed at returning hostages and stabilizing the region.

After Israeli forces conducted a military campaign following the October 2023 attack that resulted in significant casualties, recent updates indicate ongoing hostilities and escalating tensions as the situation remains precarious.
