A child has drowned at sea after a dinghy carrying people from the Turkish coast capsized during a crossing to Lesbos island in Greece.
It marks the first death since Turkey opened its border so migrants and refugees could leave for Europe and comes as Greek police fired tear gas at migrants trying to get through the land border.
The Greek coast guard claimed 46 migrants on a dinghy heading to the island of Lesbos, accompanied by a Turkish patrol vessel while in Turkish waters, overturned deliberately once in Greek waters.
The incident sparked a rescue operation and the coast guard said they rescued the migrants, which included two children who were taken to hospital - one of them unconscious.
Resuscitation efforts on the unconscious child, a boy aged six or seven, failed, while the other child's condition is not believed to be life-threatening.
The Turkish president Recep Tayyip Erdogan is said to be aiming to pressure Europe into offering Turkey more support in dealing with the fallout from the Syrian war to its south.
More than 10,000 migrants, mainly from Syria, other Middle Eastern states and Afghanistan, have reached Turkey's land borders with EU states Greece and Bulgaria since last Thursday.
Today, thousands of migrants continued to find a way across Turkey's land border into Greece, which has made clear its borders will remain closed.
Greek and Turkish police fired tear gas into stone-throwing crowds caught between the fences in no man's land.
Dozens managed to pass through border fences as others reached Greek islands from the Turkish coast by boat, while some others attempted swimming across the Evros river.
Greek police said that at least 1,000 migrants reached Greece's eastern Aegean islands since yesterday morning.
