A spokesperson for Gaza’s Hamas-run Civil Defence agency – the strip’s main emergency response service – told the BBC that at least 34 Palestinians have been killed and 70 others injured.
The Israel Defense Forces (IDF) said it was targeting what it called “terror targets” belonging to Hamas.
This is the largest wave of airstrikes in Gaza since the ceasefire began on January 19. Talks to extend the Gaza ceasefire have failed to reach an agreement.
Three houses were hit in Deir Al-Balah in central Gaza, a building in Gaza City, and targets in Khan Younis and Rafah, Reuters reported, citing medics and witnesses.
Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz ordered the strikes on Tuesday morning, according to a statement from the PM’s office.
“This follows Hamas’s repeated refusal to release our hostages, as well as its rejection of all of the proposals it has received from US Presidential Envoy Steve Witkoff and from the mediators,” it said.
“Israel will, from now on, act against Hamas with increasing military strength,” it added.
The plan for the strikes “was presented by the IDF over the weekend and approved by the political leadership,” it said.
US President Donald Trump’s administration was consulted by Israel prior to carrying out the strikes, a White House spokesperson told Fox News.
Negotiators have been trying to find a way forward after the first phase of the temporary truce ended on March 1.
The US proposed extending the first phase until mid-April, including a further exchange of hostages held by Hamas and Palestinian prisoners held by Israel.
But a Palestinian official familiar with the talks told the BBC that Israel and Hamas disagreed over key aspects of the deal set out by Witkoff at the indirect talks.
