At least 13 migrants have been killed, following a collision between their dinghy, and a ferry, off the coast of Turkey.
At least 13 migrants, including children, have died after their dinghy and a ferry collided off Turkey, the coastguard there says.
The accident happened close to the port of Canakkale. The boat was on its way to the Greek island of Lesbos.
In a second incident, Greece’s coastguard said 26 people were feared missing from a boat, also off Lesbos.
Meanwhile thousands of migrants continue to cross borders in southern Europe, many now passing into Austria.
Turkey’s coastguard said it had raised the alarm after being told that a commercial vessel and a migrant boat had collided off Canakkale.
It said it had sent a helicopter and six rescue boats to the area.
Eight people have been rescued, with one seriously injured. Some reports said four of the dead were children.
One survivor who gave his name as Haseen, told AFP news agency: “It was dark, we saw the ship bearing down on us. We tried to signal with flashlights and cell phones but they did not see us.”
The passengers were thrown into the water.
“We lost the children. We could not see them in the dark,” Haseen said.
In the second incident, Greece’s coastguard said it had rescued 22 people spotted in the water near Lesbos – but a further 26 people were feared missing.
On Saturday, a five-year-old girl died and 13 people were feared missing after their boat also sank off Lesbos.
Trips on makeshift craft between Turkey and Greek islands are frequent and dangerous for migrants, many of whom are fleeing conflict in Iraq, Syria and Afghanistan.
