Turkish coastguard officials recovered bodies washed up on a beach after yet another migrant boat trying to reach Europe sank, leaving up to 37 dead, according to local media.

In harrowing scenes reminiscent of Aylan Kurdi, the Syrian toddler photographed lying dead on a Turkish beach in September, the tiny body of a baby could be seen among those lying on a beach near the town of Ayvacik in northwestern Canakkale province, a photographer at the scene said.

Another baby was found dead in the water.

Several other young children also drowned after the boat ferrying them and their families - some from Syria, others from Afghanistan and Myanmar - to the nearby Greek island of Lesbos sank just off the Turkish coast.

State-run Anatolia news agency said 33 people died in the tragedy, which comes two days after 25 migrants, including 10 children, drowned off the Greek island of Samos.

A further 75 people were rescued today by the coastguard, Anatolia said.

"We are sad. At least 20 friends are still missing," a survivor said earlier, weeping.

The capsized boat was visible around 50 metres from the shore, where divers from the coastguard were still searching for the missing.

The drownings continue the grisly trend that accelerated last year when nearly 4,000 people died trying to reach Europe by sea, according to the International Organisation for Migration (IOM).

The influx, which has been fuelled by Syria's civil war, has continued throughout the winter.

During the first 28 days of 2016, a further 244 migrants died at sea, with at least a dozen more dying on land, the IOM said.

Turkey, which is hosting at least 2.5 million refugees from Syria's civil war, has become the main launch-pad for migrants fleeing war, persecution and poverty to Europe. 

The Turkish government struck a deal with the EU in November to halt the outflow of refugees, in return for €3bn in financial assistance, but the agreement has failed to check the migrant tide.

German Chancellor Angela Merkel said yesterday that, with 2,000 new asylum seekers entering the Balkans on their journey to northern Europe every day, the EU "urgently" needed to implement its side of the agreement.

Italy has however questioned how much of the money should come from the EU budget, and how much control the bloc will have over how Ankara spends the funds.

Turkey's minister for EU affairs Volkan Bozkir dismissed any problems with Italy about the release of the EU money and said the funds would be released in February.
