Search operations are continuing to find other missing migrants, a member of Libyan Red Crescent told Reuters by phone.
It was unclear how many people were on board and how many are still missing and feared to have been drowned after what the UN refugee agency UNHCR described as “the worst Mediterranean tragedy of this year.”
Red Crescent member Abdulmenam Abu Sabay said the boat, which capsized near Komas, some 120 kilometres east of Tripoli, was carrying 350 people, mostly from Sub-Saharan Africa.
The Libyan navy on Thursday put the number of migrants on board at 250 and the UNHCR said up to 150 were feared dead.
Libyan coast guards and local fishermen rescued 134 migrants on Thursday.
"We do not have enough capability to carry out our operations. Citizens help us with their own vehicles,” Abu Sabay said.
"The bodies are still in bags in a hangar and we are waiting for security authorities' permission to bury them,” he added. The hangar belongs to a department set up to fight illegal migration.
Libya is a hub for migrants and refugees, many of whom try to reach Europe in unseaworthy boats.
