Nine children were among 57 migrants in a wooden boat intercepted Saturday about 40 nautical miles from the town of Zuwara, west of Tripoli, navy spokesman General Ayoub Kacem told AFP. He said they were from Ethiopia and Egypt.
It came days after Libyan navy patrols on Tuesday "rescued 278 migrants on board four inflatable boats northwest and northeast of Tripoli", Kacem added.
The operations took place off the coasts of the cities of Khoms, 120 kilometres (75 miles) east of Tripoli, and Sabratha, located 70 kilometres west of the capital.
According to the statement, 128 Sudanese were in the boats, in addition to migrants from Chad, Egypt, Niger, Benin and Eritrea, including 35 women and 11 children.
One body was also recovered by the coastguard.
