ISTANBUL: Turkish authorities on Tuesday found the dead bodies of at least 36 migrants, including several children, washed up on beaches and floating in the sea off its western coast after their boats sank while crossing the Aegean Sea to European Union (EU) member Greece.

The tragedies, the deadliest so far reported in the Aegean in 2016, come as the EU seeks to push Turkey to halt the flow of migrants across its borders in exchange for financial help.

A spokesman for the Turkish coastguard told AFP that the bodies of 36 migrants had been found, including 29 recovered by the Turkish gendarmerie and seven by the coastguard.

It was not immediately clear how many boats had sunk in the high seasonal winds although the Dogan news agency said at least two separate incidents were involved.

The dead bodies were found either washed up on the beach near the resort of Ayvalik or in the sea nearby, Dogan said. Eight more migrants had been rescued.

Among those found dead was a woman who was six months pregnant.

Images published by Dogan showed the small corpses of children, fully dressed and wearing shoes, lying on the beach with their life-jackets still on.

Video footage showed Turkish security forces lifting other bodies from the waves in the shallows on the shore.

In a second disaster, seven migrants were found dead off the resort of Dikili just to the south, it added. The victims there also included women and children, Dogan said.

'Over million reach Europe'

The tragedies are the latest involving migrants fleeing war and misery in the hope of finding a new life in Europe.

The images of the small lifeless bodies on the sand echo those of three-year-old Syrian refugee Aylan Kurdi, pictures of whose corpse lying face down on a Turkish beach in September 2015 spurred Europe into greater action on the migrant crisis.

A drowned two-year-old boy became the first known migrant casualty of the year on Saturday after the crowded dinghy he was travelling in slammed into rocks off Greece's Agathonisi island, the coastguard said.

Turkey, which is home to some 2.2 million refugees from Syria's civil war, has become a hub for migrants seeking to reach Europe, many of whom pay people smugglers thousands of dollars for the risky crossing.

The International Organization for Migration (IOM) said 1,004,356 migrants and refugees reached Europe in 2015, almost five times the previous year's total of 219,000.

The IOM also said Tuesday that 3,771 migrants and refugees died crossing the Mediterranean trying to reach Europe in 2015, making the past year the deadliest on record.

It said 77 per cent of the deaths occurred in the central Mediterranean route mostly used by smugglers operating from Libyan shores. But it noted a surge in the numbers who died in the eastern Mediterranean around Turkey and Greece.

“In 2015, 21 per cent of deaths occurred in the eastern Mediterranean compared to only 1 per cent in 2014,” the IOM said.

Ankara reached an agreement with the EU in November to stem the flow of refugees heading to Europe, in return for financial assistance.

Brussels vowed to provide $3.2 billion in cash as well as political concessions to Ankara in return for its cooperation in tackling Europe's worst migrant crisis since World War II.

But onset of winter and rougher sea conditions do not appear to have deterred the migrants, with boats still arriving on the Greek islands daily.

The IOM said it estimated that in the first three days of 2016 alone just over 5,000 migrants and refugees crossed into Greece.

Citizens of Syria and Afghanistan accounted for almost 80 percent of these migrants with others coming from Iraq, Iran and the Palestinian Territories, it said.
