TEL AVIV – The Israeli military has intercepted a Gaza-bound aid ship seeking to break the Israeli blockade of the Palestinian territory, detaining 21 international activists and journalists and seizing all cargo, including baby formula, food and medicine, the Freedom Flotilla Coalition said Sunday.

The coalition that operates the vessel Handala said the Israeli military “violently intercepted” the ship in international waters about 40 nautical miles from Gaza, cutting the cameras and communication, just before midnight Saturday.

“All cargo was non-military, civilian and intended for direct distribution to a population facing deliberate starvation and medical collapse under Israel’s illegal blockade,’’ the group said in a statement.

The Israeli military had no immediate comment. Israel’s Foreign Ministry posted on X early Sunday that the Navy stopped the vessel and was bringing it to shore.

It was the second ship operated by the coalition that Israel has prevented in recent months from delivering aid to Gaza, where food experts have for months warned of the risk of famine. Activist Greta Thunberg was among 12 activists on board the ship Madleen when it was seized by the Israeli military in June.

The ship’s interception comes as Israel faces mounting international criticism over the worsening humanitarian situation in Gaza, with concern growing over rising hunger in the territory amid Israeli restrictions on aid.

A regional human rights group, Adalah, said the raid on the vessel violated international law. It demanded the immediate release of the 21 activists, including lawmakers and human rights campaigners, from 10 countries.

“The flotilla never entered Israeli territorial waters, nor was it intended to do so; it was headed toward the territorial waters of the State of Palestine, as recognized under international law,” Adalah said in a statement. “Israel has no legal jurisdiction or authority over the international waters in which the vessel was sailing.”

Adalah demanded immediate disclosure of the activists’ location and legal status.

Lawmaker Nicola Fratoianni, of a left-wing environmentalist party, called on the Italian government to ensure the safety of the two Italians on board.

Also on board were seven U.S. citizens, including a human rights attorney, a Jewish U.S. war veteran and a Jewish-American activist, according to the Freedom Flotilla Coalition.
