Israel carried out an airstrike on September 9, 2025, in Doha, Qatar, targeting high-ranking Hamas officials involved in ceasefire negotiations. The attack, authorized by Israeli Prime Minister Benjamin Netanyahu, killed six people, including Hamas negotiators and a Qatari security officer, while injuring others. The strike caused diplomatic tensions as Qatar, a key US ally and mediator in Gaza peace talks, condemned the attack as a breach of its sovereignty. US President Donald Trump expressed regret over the incident, emphasizing that the decision to strike was made by Netanyahu and not him. Trump reaffirmed the US goal of eliminating Hamas but criticized the strike for undermining US-Qatar relations. Qatar insisted it had no prior knowledge of the attack and vowed to respond accordingly. The event threatens ongoing peace efforts and raises questions about US diplomatic coordination.
