There are 300 missing and several confirmed dead from the May 26 migrant shipwreck off the coast of Libya, the Italian Coastguard says.
The estimate was made after survivors were interviewed after arriving in several Italian ports, a press officer, who cannot be quoted by name, tells dpa.
The official says there were two boats, one towing the other, each with about 450 people on board. The second vessel sank after its tow cable was cut, and only about 150 of its passengers were rescued.
Rescue units also recovered some bodies, but the coastguard cannot give an exact number.
