Israeli Prime Minister Benjamin Netanyahu has apologised to his Qatari counterpart for Israel's attack in Doha during a telephone call from the White House on Monday, a source close to Netanyahu told Reuters.

The call to the Qatari Prime Minister Mohammed bin Abdulrahman Al Thani came as Netanyahu met with US President Donald Trump in Washington.

According to White House, Netanyahu told Qatar that Israel “will not conduct such an attack again in the future”.

Qatari premier 'welcomed' Netanyahu's assurances, a statement from White House read.

A Qatari technical team is also at the White House, according to a separate source briefed on the talks.

A diplomat, speaking to AFP on condition of anonymity, said Netanyahu voiced regret for the violation of Qatari sovereignty and the death of a Qatari security guard in the September strikes.

Israel struck a building in the Qatari capital that housed family members of the Hamas ceasefire negotiating team on September 9, killing five Hamas members and a Qatari security officer.

Hamas said Israel aimed to kill its negotiating team that was reviewing a ceasefire proposal to end the war in Gaza, where Israel has killed over 66,000 people since October 2023.

The attack drew widespread international condemnation, including from Gulf states allied with the United States, Israel's main backer.

Qatar plays a mediation role in the Gaza war alongside the United States and Egypt.

Qatar swiftly condemned what it called a "cowardly" Israeli attack on its soil, saying the strike represented "a flagrant violation of all international law".
