A global flotilla led by Greta Thunberg returns to Barcelona due to weather, aiming to challenge Gaza's blockade.

A flotilla carrying humanitarian aid to Gaza, led by figures like Greta Thunberg, was forced to return to Barcelona due to dangerous weather conditions. The mission aims to challenge Israel's blockade of Gaza, which has faced interceptions by Israeli forces in the past. The humanitarian crisis in Gaza has worsened, with famine declared in parts of the enclave. The flotilla, involving over 50 boats from 44 countries, is the largest attempt to date to deliver aid to the region.
