The Madleen ship, carrying 12 activists including climate campaigner Greta Thunberg, set out from Sicily on June 1 to deliver humanitarian aid to Gaza amid a strict Israeli blockade lasting over 90 days. The 2,000km journey is tracked live, with the latest position near Crete on June 4. Israel’s military has warned it will block the ship, risking detention and seizure if the activists don’t comply. Gaza faces severe food shortages and heavy bombardment casualties.
