"Our conference is sending a powerful message, we are not letting down the people of Syria," EU Humanitarian Aid Commissioner Christos Stylianides told delegates.
"Delegations present here today have made a collective pledge of USD 6 billion for this year alone," he said to applause at the EU-UN-hosted conference.
"Thank you so much. It is an impressive figure," he added.
Stylianides did not clarify if the funding was new, or if it included some funds previously pledged by the international community for war-torn Syria.
