Italy’s navy will stop following the international flotilla trying to deliver aid to Gaza once it gets within 150 nautical miles (278 km) of the shore, the Italian defense ministry said on Tuesday.

The Global Sumud Flotilla, consisting of more than 40 civilian boats carrying parliamentarians, lawyers and activists, including Swedish climate campaigner Greta Thunberg, aims to break Israel’s blockade of the Palestinian enclave.

Once the convoy reaches the 150 nautical miles limit, the Italian frigate accompanying it will stop, “as communicated several times in recent days,” the ministry said in a statement.

The ship, Alpino (F-594), will issue two warnings to activists, with the second and final one foreseen at around 00:00 GMT, when the flotilla is expected to get within the stated distance, the statement added.

Earlier on Tuesday, an Italian spokeswoman for the flotilla, Maria Elena Delia, said that activists had been informed about the government’s plans to have the navy ship stop and turn back to avoid “a diplomatic incident” with Israel.

She said the flotilla had no intention of heeding Italy’s warnings not to get closer to the shore.

Italy and Spain deployed navy vessels last week to assist the flotilla, after it was hit by drones armed with stun grenades and irritants in international waters off Greece, but without any intention to engage militarily.

Delia said activists were bracing for another strike in the coming hours.

“Israel will probably attack us tonight, because all the signals point to this happening,” she said in a video on Instagram.

Israel did not respond to flotilla accusations that it was behind last week’s attacks, but it has vowed to use any means to prevent the boats from reaching Gaza, arguing that its blockade is legal as part of its war against Hamas terrorists.

Italian Defense Minister Guido Crosetto has said he expects flotilla boats to be intercepted in the open sea and activists to face arrest.

On Tuesday, Crosetto made a “last appeal” to flotilla members to accept a compromise proposal to drop aid in Cyprus from where it would be delivered to Gaza and avoid a confrontation with Israeli forces. Flotilla representatives have repeatedly refused the offer, which Israel had backed.

Israel imposed a blockade on Gaza in 2007, saying it was a bid to stop the import of weapons after the Hamas terror group overthrew the Palestinian Authority and took control of the enclave.

Israel has come under huge international pressure over its war in Gaza.

Israel began its Gaza offensive after the October 7, 2023, Hamas-led attack on Israel, which killed 1,200 people and saw 251 taken as hostages back to Gaza. Of those, 48 remain in captivity, 20 of them believed alive.

The war has sparked a humanitarian crisis in the Strip, with most of the population displaced.
