Gibraltar ship stripped of flag amid dispute over migrants stranded at sea

The search-and-rescue ship Aquarius rescued migrants off the coast of Libya on August 10.

(CNN)Gibraltar has moved to strip a stranded migrant rescue ship of its registration amid a row over which country is responsible for taking in the 141 desperate migrants, including dozens of children, on board.

      "It is well-established that responsibility for arranging disembarkation, at a nearby safe port, is assumed by the relevant regional Maritime Rescue and Co-ordination, and in accordance with the wishes of the ship's Master," said a government spokesperson in a statement.

      The humanitarian ship, operated by charities SOS Méditerranée and Doctors Without Borders (MSF), remains on standby in the sea between Malta and Italy, awaiting further guidance.
