The German humanitarian group Sea-Watch says the ship it operates in the central Mediterranean Sea has rescued 64 migrants in waters off Libya.

Sea-Watch wrote Wednesday on Twitter that the people brought to safety from a rubber dinghy included 10 women, five children and a newborn baby.

The group said it carried out the rescue off the coast of Zuwarah after Libyan authorities couldn't be reached. Sea-Watch is asking Italy or Malta to open a port to the rescue ship, the Alan Kurdi.

Both countries have refused to accept ships that humanitarian groups have patrolling the Mediterranean. The embargos have led to dayslong delays in getting rescued migrants to land while European countries haggle over which will take them.

Sea-Watch says it still is searching for 50 migrants missing since Monday.
