The Italian coastguard and other boats rescued some 3,000 migrants from unseaworthy boats off the Libyan coast on Saturday, as the good weather pushes the numbers up, a participating NGO said.

In all 35 rescue operations were launched during the day, with 15 of them still underway as night fell, the coastguard said.

German NGO Jugend Rettet, which took part in the rescue operations on Saturday, said 3,000 people had been plucked to safety during a particularly busy day due to the fine Spring weather in the Mediterranean.
