The Qatari Prime Minister condemned Israel's strike on Doha Tuesday, calling it an act of “state terror.”

Sheikh Mohammed bin Abdulrahman Al Thani called out Israeli Prime Minister Benjamin Netanyahu by name, saying “these barbaric actions only reflect the barbarism of this person, who is dragging the region to a place where it unfortunately cannot be repaired.”

He said Qatar would “spare no effort” to stop the war in the Gaza Strip.

But he added: “concerning the current talks, I don’t think there is anything valid now after we see an attack like that.”

He also denied the U.S. had given adequate warning, saying Qatar was only informed about the attack 10 minutes after it began.

Israel struck the headquarters of Hamas’ political leadership in Qatar on Tuesday as the group’s top figures gathered to consider a U.S. proposal for a ceasefire in the Gaza Strip.

The strike on the territory of a U.S. ally marked a stunning escalation and risked upending talks aimed at winding down the war and freeing hostages.

The attack angered Qatar, an energy-rich Gulf nation hosting thousands of American troops that has served as a key mediator between Israel and Hamas throughout the 23-month-old war and even before.

It condemned what it referred to as a “flagrant violation of all international laws and norms” as smoke rose over its capital, Doha. Other key U.S. allies in the Gulf, Saudi Arabia and the United Arab Emirates, promised their support to Qatar.

The United States said Israel alerted it before the strike, but American officials sought to distance the U.S. from the attack.

The White House said President Donald Trump believes the strike was an “unfortunate incident” that didn’t advance peace in the region.

Press secretary Karoline Leavitt said Trump spoke to Israeli Prime Minister Benjamin Netanyahu and “made his thoughts and concerns very clear.”
