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.

The environmental campaigner was sent home after she and others on the intercepted ship said they were trying to deliver food and medical supplies.

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.
