On July 31, 2024, Al Jazeera’s Ismail al-Ghoul was reporting from the Shati refugee camp in Gaza. Israel had just assassinated Ismail Haniyeh, head of Hamas’s political bureau and a negotiator in the Gaza ceasefire talks, in Iran. Israel’s killing left many bracing for a regional war, and the reporter headed to Haniyeh’s former home along with cameraman Rami al-Rif to cover the developing story. As they reported, the Israeli military carried out a strike on a nearby house. Al-Ghoul and al-Rif were asked to leave the area; they complied. Wearing blue press vests, they got in a car that also clearly identified them as press. Israel launched a missile strike on the car, killing both men. Photos of the aftermath showed al-Ghoul’s headless body still wearing the blue press vest.

It was never much of a mystery who launched the missile, but a day after the gruesome murder, Israel took credit. The official account of the Israeli military boasted that they had “eliminated” al-Ghoul. Preposterously, the post claimed that al-Ghoul was a Hamas operative who “instructed other operatives on how to record operations and was actively involved in recording and publicizing attacks against IDF troops,” a claim vehemently denied by Al-Jazeera.

Throughout its 10-month war on Gaza, Israel has killed a staggering number of journalists. According to the Palestinian Journalists Syndicate, 160 journalists and media workers have perished at the hands of Israel. This is the largest number of journalists killed during a war in recorded history. By comparison, 69 journalists were killed during World War II, and 63 journalists were killed during the Vietnam War.

By arming Israel, the State Department bears responsibility for its killing of journalists. That is why we, as leaders of organizations dedicated to defending press freedom and free expression, have organized a coalition of journalists and journalism advocates to coauthor a letter to US Secretary of State Antony Blinken, calling on the United States to impose an arms embargo on Israel immediately.

More than 100 journalists, including four Pulitzer Prize winners, along with 18 news outlets and seven press freedom organizations, most of them American, have come together to take a stand in solidarity with their fellow journalists in Palestine and against US complicity in their intentional killing.

The high number of journalists killed is part of the shocking death toll. Gaza is one of the most densely populated places on Earth and Israel has unleashed a bombing campaign that has exceeded the destruction of the Allied bombing of Dresden. Within the first month of the war alone, Israel dropped explosives on Gaza that were equivalent to two nuclear bombs in terms of tonnage. This genocidal bombardment has led to nearly 40,000 deaths.

But it isn’t just Israel’s indiscriminate killings that have resulted in the unprecedented killing of journalists. By Israel’s own admission, al-Ghoul was targeted directly. The Palestinian Journalists Syndicate filed an amicus brief in support of an American lawsuit charging the Biden administration with violating the Genocide Convention. In the brief, they stated, “Evidence strongly indicates that the vast majority of the journalists and media workers killed since the start of the genocide were specifically targeted for assassination by the Israeli military.” Al Jazeera similarly has accused Israel of assassinating its journalists. While the scale of Israel’s killing of journalists is without precedent, Israel has a longer history of targeting Palestinian journalists. Israeli snipers were credibly accused of intentionally targeting journalists during the 2018 Great March of Return and independent investigations have found evidence that in 2022 intentionally killed Al Jazeera reporter Shireen Abu Alkeh.

Israel’s assassination of journalists, like its wider military actions, are made possible by US support. The US provides the weapons and uses its diplomatic and political clout to make sure Israel is sheltered from any accountability when it uses those weapons to violate international law.

“Israel’s military actions are not possible without US weapons, US military aid, and US diplomatic support,” we write. “By providing the weapons being used to deliberately kill journalists, you are complicit in one of the gravest affronts to press freedom today.”

The letter’s signers include some of the most well-known and most decorated journalists of our time: Laura Poitras, Kai Bird, James Bamford, Spencer Ackerman. Many of the signatories are contributors to the Nation and Jacobin. The journalists are joined by entire newsrooms, including Middle East Eye, Current Affairs, Mondoweiss, Drop Site News, Truthout, In These Times, Antiwar.com, and The Real News,and press freedom groups like the Courage Foundation, Defending Rights & Dissent, Roots Action, Project Censored, and Freedom of the Press Foundation. These influential reporters, outlets, and free-expression advocates recognize that Israel’s killing of reporters in Gaza, who brave endless airstrikes, tanks, and snipers to show the world what’s happening, is a deliberate effort to shield their assault on Palestinians from global scrutiny—and therefore to shield themselves from international accountability.
