The Turkish coast guard saved 21 people on Thursday after a wooden boat capsized near Dikili, located across from the Greek island of Lesbos.

The deaths are the latest this week, which saw a plastic boat carrying migrants sink off the Greek island of Farmakonissi , drowning at least 13 including children. In another tragedy on Tuesday 11 migrants drowned.

More than one million migrants have arrived in Europe this year, of whom some 820,000 have made the dangerous trip by boat from Turkey to Greece, the Geneva-based the International Organization for Migration said earlier this week. It said at least 3,692 migrants have died at sea this year.

Turkey, which hosts more than 2 million refugees from Syria and is a transit point for migrants from Afghanistan and Iraq, is a major gateway for people trying to make their way to Europe.

To stem the flow of migrants, the EU and Turkey agreed on a 3 billion euros ($3.2 billion) aid package last month as well as political concessions to Ankara.

In exchange, Turkey is to improve refugee camps and take steps to better integrate Syrians while cracking down on human traffickers.

Since the November deal Turkish police and coast guard have reportedly arrested smugglers and rounded-up would-be migrants.

The number of migrants making the sea journey has also dropped from earlier this year due to winter weather and rough seas.
