Relations between Israel and Turkey have sharply deteriorated since the war in Gaza erupted after Palestinian Islamist movement Hamas's attacks on Israel in October 2023.

"A historic decision: the Israeli government has unanimously approved Foreign Minister Gideon Saar's proposal to recognise the Armenian genocide," the foreign ministry said.

The cabinet's decision must still be ratified by parliament.

Successive Israeli governments had avoided formally recognising the Armenian genocide, in part to preserve relations with Turkey, once one of Israel's closest strategic partners in the region.

But since the war in Gaza erupted, Turkey has regularly accused Israel of committing genocide in the Palestinian territory, an accusation Israel strongly denies.

Turkish President Recep Tayyip Erdogan has emerged as one of the fiercest critics of the war, repeatedly comparing Israeli leaders to Nazi officials.

Israeli Prime Minister Benjamin Netanyahu has also hit back at Erdogan, calling him an "anti-semitic dictator who commits genocide against the Kurds".

Turkey has suspended most trade with Israel and become one of Hamas's strongest diplomatic supporters.

The Armenians seek international recognition that the mass killings of their people under the Ottoman Empire from 1915 to 1917 amounted to genocide.

They say 1.5 million died, but Turkey strongly denies the accusation of genocide and says that both Armenians and Turks died as a result of the First World War.

It puts the death toll in the hundreds of thousands.

The killings have been recognised as genocide by more than two dozen countries, including the United States, France and Germany.

Former US president Joe Biden recognised the killings as genocide, a position long sought by Armenia.

His successor President Donald Trump has not used the same terminology.

Armenia and Turkey have no diplomatic ties, but the two have signalled interest in warming relations in recent years.
