A German-owned general cargoship took on board 151 migrants late on 8 September, Greek coastguards reported on Wednesday.
The migrants were drifting on a yacht 5.5 nautical miles (10 km) northeast of the Aegean island of Amorgos when the 10,900-dwt Jork (built 2010) picked them up, Greek coastguards said.
The operation took place under adverse weather conditions of fresh gale-strong winds measuring up to 8 on the Beaufort scale.
