Hundreds of pro-Palestinian activists in a Gaza-bound convoy reached the Libyan capital of Tripoli on Wednesday as they drive eastward in a bid to break Israel's blockade of the Palestinian territory.

Organizers say climate campaigner Greta Thunberg and other 11 activists set sail on Sunday afternoon for Gaza on a ship aimed at “breaking Israel’s siege” of the devastated territory.

A Gaza-bound boat carrying Greta Thunberg and other international activists was intercepted by Israeli forces in international waters. The group was attempting to deliver humanitarian aid to Palestinians as part of a protest flotilla.
