Spanish Prime Minister Pedro Sanchez has said his country's navy will join Italy in sending warships to protect the Global Sumud Flotilla, which has come under drone attack in international waters en route to deliver aid to Gaza. Speaking to reporters in New York on Wednesday, where he is attending the United Nations General Assembly (UNGA), Sanchez said international law must be respected and the citizens of 45 nations participating in the aid mission had every right to sail in the Mediterranean unharmed.
