An EU border patrol boat sank in the Aegean Sea Monday during a migrant search, the Greek coastguard said, adding that the crew were immediately picked up by other vessels.

The Frontex boat sank after hitting a reef near the island of Lesbos, a coastguard officer told AFP.

“It was taking part in a search for migrants in the area, in near gale wind conditions,” he said.

The Frontex vessel crew of five Portuguese and a Greek national is in good health, he added.

The search had begun after 36 migrants, spotted by police on a Lesbos beach, told authorities that others among their group were missing at sea.

So far no one has been found but the search is ongoing, the coastguard said.
