The European Union is dedicating 2.01 billion euros (2.27 billion dollars) in aid for the Syrian crisis this year - including 1.5 billion euros pledged for refugees in Turkey alone - foreign policy chief Federica Mogherini tells a donors' conference.
The bloc has earmarked 560 million euros in 2019 to support the population in Syria and those who have fled to neighbouring countries - notably Jordan and Lebanon - as well as helping host communities, Mogherini says. Member states are due to contribute separately.
German Development Minister Gerd Mueller says his country's contribution will be 1.44 billion euros this year, describing this as a "strong sign of solidarity." The figure is marginally below Germany's 2018 pledge.
"If we get to close to - or even a bit better than - the 6 billion dollars that we raised last year for our appeals, then that will be a good day," UN humanitarian chief Mark Lowcock said ahead of Thursday's pledging session.
Turkey hosts more than 3.5 million Syrian refugees, more than any other country in the world.
Syria has been locked in a vicious civil war since early 2011, when the Assad regime cracked down on pro-democracy protests.
Since then, hundreds of thousands of people have been killed and more than 10 million others displaced, according to UN officials.
