The activists had set out to protest Israel’s ongoing military campaign in the Gaza Strip, which is among the deadliest and most destructive since World War II, and its restrictions on the entry of aid.

All 12 people from an aid boat intercepted by Israel carrying Swedish climate advocate Greta Thunberg have arrived at port and are being transferred to the custody of Israeli authorities, the group involved said in a social media post.

The detained crew of the Gaza-bound aid ship that was intercepted by Israel on Monday morning has been taken to the Israeli port of Ashdod, according to Israel’s foreign ministry.
