LONDON -- The Israeli Foreign Ministry said early Monday that Israeli forces had boarded and diverted a privately owned ship carrying Swedish human rights activist Greta Thunberg and several others, who said they were attempting to bring humanitarian aid to the Gaza Strip.

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.
