Cyprus police said Sunday that four vessels appeared off Cyprus' eastern and southern coast over the last two days carrying a total 123 migrants and about half of them have been permitted to disembark.

Some 21 migrants remain aboard a boat that is adrift off Cyprus' southeastern tip as a result of a faulty engine. Police said three women and nine children had earlier been taken off the boat and transferred to a Cypriot hospital as a precaution. Some 33 migrants aboard a boat that police intercepted 14 miles (22.5 kilometers) off the southern coast Saturday afternoon have boarded another vessel that Cypriot authorities have chartered to be taken back to Lebanon.

European Union member Cyprus and Lebanon have an agreement to curb the arrival of boats loaded with migrants from reaching the island. On Friday, police encountered a small craft sailing off the coastal town of Larnaca with five migrants aboard. The boat continued to sail on in an undetermined direction.

Meanwhile, 51 migrants were to a reception center after their boat from Lebanon reached a rocky beach Saturday along the island's eastern coastline that's inside a U.N. controlled buffer zone separating ethnically split island's breakaway Turkish Cypriot north from the internationally recognized Greek Cypriot south. UN peacekeepers transferred the 35 men, five women and 11 children to Cypriot custody. A court on Sunday ordered that four men remain in custody over suspicion they were the boat's crew.

Police said another 20 Syrian migrants — 19 men, a woman and a child — were taken to a reception center after being picked up Sunday morning near the buffer zone 10 miles (16 kilometers) west of the capital Nicosia.
