A court in Istanbul has ordered 15 of 34 people detained on suspicion of spying for Israel be held in prison awaiting trial, Turkiye’s justice minister said late Friday.

The suspects were arrested on Tuesday for allegedly planning to carry out activities that included “reconnaissance” and “pursuing, assaulting and kidnapping” foreign nationals living in Turkiye.

Justice Minister Yilmaz Tunc said in a social media post that 26 suspects were referred to the court on a charge of committing “political or military espionage” on behalf of Israeli intelligence. Eleven were released under judicial control conditions and eight were awaiting deportation.

Israel’s foreign intelligence agency Mossad is said to have recruited Palestinians and Syrian nationals inside Turkiye as part of the operation against foreigners living in Turkiye, state-run Anadolu news agency reported.

The agency cited a prosecution document as saying the operation targeted “Palestinian nationals and their families … within the scope of the ongoing Israeli-Palestinian conflict”.

One suspect allegedly collected information about Palestinian patients recently transferred to Turkiye for health care. Turkiye has accepted dozens of Palestinian patients from Gaza since the start of the Israel-Hamas conflict.

The suspects were detained in raids on 57 addresses in Istanbul and seven other provinces. Weeks earlier, the head of Israel’s domestic Shin Bet security agency said his organisation was prepared to target Hamas anywhere, including in Lebanon, Turkiye and Qatar.

Turkish President Recep Tayyip Erdogan warned Israel of “serious consequences” if it pressed ahead with its threat to attack Hamas officials on Turkish soil.

Turkiye and Israel had normalised ties in 2022 by reappointing ambassadors following years of tensions. But those ties quickly deteriorated after the Israel-Hamas war, with Ankara becoming one of the strongest critics of Israel’s military actions in Gaza.

Israel initially withdrew its diplomats from Turkiye over security concerns and later announced it was recalling its diplomats for political reasons, citing “increasingly harsh statements” from Turkish officials. Turkiye also pulled out its ambassador from Israel.

Erdogan’s reaction to the Israel-Hamas war was initially fairly muted. But the Turkish leader has since intensified his criticism of Israel, describing its actions in Gaza as verging on “genocide”.

He has called for Israeli Prime Minister Benjamin Netanyahu to be prosecuted for “war crimes” and compared him to Nazi leader Adolf Hitler.

Erdogan, whose government has hosted several Hamas officials in the past, has also said the militant group — considered a terrorist organisation by Israel, the United States and the European Union — is fighting for the liberation of its lands and people.
