Gaza's already fragile ceasefire is under severe strain after Israeli air strikes killed 44 Palestinians in response to attacks by Hamas that left two Israeli soldiers dead. Israel has suspended the transfer of humanitarian aid into Gaza, citing repeated ceasefire violations by Hamas, including attacks on soldiers and alleged executions of Palestinian civilians accused of collaborating. The Israeli government has warned of increased military action if the ceasefire is not respected and has tied the reopening of aid routes to the return of all deceased hostages held by Hamas. Tensions remain high as both sides trade accusations over responsibility for the renewed violence.
