MILAN :A merchant ship has supplied fuel and water to a boat with around 400 migrants on board which is in distress between Greece and Malta but Maltese authorities have ordered it not to conduct a rescue, German NGO Sea-Watch International said on Monday. Alarm Phone said the boat was in the Maltese Search and Rescue area (SAR). "If the boat keeps moving, it might reach Italy and Malta does not have to accept the people," it said on its Twitter account. According to press agency ANSA, on Sunday almost 1,000 migrants arrived in the Italian island of Lampedusa, south of Sicily.
