A boat carrying activists, including two Australians, has been intercepted by Israeli forces, Israel's foreign ministry has confirmed.
A pro-Palestinian activist group claims the crew of the vessel, dubbed Handala, is being held in "unlawful" detention after attempting to deliver humanitarian aid to Gaza.
According to the Freedom Flotilla Coalition, the vessel was carrying 21 activists, including Australian journalist Tan Safi and activist Robert Martin, when it was stopped in international waters about 40 nautical miles from Gaza.

The scene was livestreamed by the group on social media and appears to show the activists holding up their hands as soldiers board the vessel before the video feed is cut.
A Department of Foreign Affairs and Trade spokesperson confirmed the two Australians were on the boat.
"DFAT is aware two Australians were on board the Freedom Flotilla Coalition vessel Handala, along with 19 others," they said.
"Our officials in Tel Aviv are liaising with authorities, and consular officers stand ready to offer assistance to affected Australians."
The refurbished fishing boat had departed from Malmö, Sweden, aiming to breach the Israeli naval blockade on Gaza and deliver aid supplies such as baby formula, nappies, food, and medicine to Palestinians in the besieged territory.
The Israeli foreign ministry said its navy had stopped the ship from "illegally entering the maritime zone of the coast of Gaza".
"The vessel is safely making its way to the shores of Israel. All passengers are safe," a post on X read.
"Unauthorised attempts to breach the blockade are dangerous, unlawful, and undermine ongoing humanitarian efforts."

"We are a non-violent movement, we are delivering aid," he said.
"To the world, if something happens, we were trying to shine a light on what's happening in Palestine and in particular, Gaza."
This incident follows a similar one on 9 June, when the Madleen, another Freedom Flotilla vessel, was intercepted by the Israeli military in international waters and towed to the port of Ashdod. That ship carried 12 campaigners, including Swedish climate activist Greta Thunberg, all of whom were later expelled from Israel.
In a more deadly episode in 2010, nine activists aboard a flotilla the Mavi Marmara were reportedly shot by Israeli soldiers. Five of them died.
