Israel-Gaza live updates: Sirens sound in Tel Aviv as Hamas fires rocket from Gaza

Hamas’ military wing, the Al-Qassam Brigades, took responsibility for an attack in Tel Aviv on Sunday evening that left one person injured and the bomber dead.

In a joint statement released Monday, Israeli Police and Shin Bet said the explosion had been a terror attack.

"It can now be confirmed that this was a terror attack involving the explosion of a powerful explosive," the Israeli police and Shin Bet said. "As a result of the explosion, a passerby was moderately injured (according to medical sources) and was transported to receive medical treatment."

American Airlines has extended their suspension of flights to and from Tel Aviv until March 29, 2025, the airline said Monday.

American Airlines said they would allow customers whose travel plans are impacted by the extension to rebook their flights without a fee or cancel and receive a refund.

"We will continue to work closely with our partner airlines to assist customers traveling between Israel and European cities with service to the U.S.," the airline said in a statement.

Journalist Ibrahim Muhareb was killed by an Israeli airstrike while on duty in the Khan Younis area on Sunday, his employer, the online newspaper BDN, said in a statement.

A video filmed by Muhareb's friend and colleague, Abdallah Alattar, showed the moment the journalist’s body -- his press vest laid on top of him -- arrived at Nasser Hospital after being found in Hamad Town early on Monday morning.

Muhareb had been covering the events in western Khan Younis with other colleagues when they were targeted, BDN said.

"His traces were lost after occupation artillery targeted a group of journalists in the place yesterday," BDN said in a statement, adding that Muhareb had been working regularly with them throughout the war while also freelancing for others.

As of Aug. 19, the Committee to Protect Journalists' preliminary investigations showed at least 113 journalists and media workers have been killed since the war began, making it the deadliest period for journalists since CPJ began gathering data in 1992. Of those killed, 108 were Palestinian, two were Israeli and three were Lebanese.

Palestinian journalists strongly protested what they say is the deliberate targeting of the media and the lack of support from international colleagues on July 31, following the killing of Al Jazeera's Ismail Al-Ghoul and Rami Al Refee by an Israeli strike while they were working in Gaza City. Israel alleges that Al-Ghoul was a member of Hamas, an allegation that the network denied.

"Even before the start of the Israel-Gaza war, CPJ had documented Israel’s pattern of accusing journalists of being terrorists without producing credible evidence to substantiate their claims," said CPJ Program Director Carlos Martínez de la Serna. "Smear campaigns endanger journalists and erode public trust in the media. Israel must end this practice and allow independent international investigations into the journalists' killings."

Secretary of State Antony Blinken met with Israeli Prime Minister Benjamin Netanyahu for three hours on Monday, Netanyahu’s press office said in a release.

The meeting was "positive and was held in a good atmosphere," the release said.

"The meeting lasted approximately three hours. The Prime Minister reiterated Israel's commitment to the current American proposal on the release of our hostages, which takes into account Israel's security needs, which he strongly insists on," the release said.

Blinken also met with Israeli President Isaac Herzog and Israeli Defense Minister Yoav Gallant on Monday, according to the U.S. State Department.

"The Secretary reaffirmed the United States’ ironclad commitment to Israel’s security and efforts to de-escalate tensions in the region," a spokesperson for the State Department said in a statement. "The Secretary reiterated the urgent need to finalize the ceasefire agreement that would release the hostages, allow a surge of humanitarian assistance, and create the conditions for broader regional stability."

Blinken is expected to head to El Alamein, Egypt, on Tuesday for additional meetings.
