Ireland has already contributed €5 million to Turkey
Minister for Foreign Affairs Charlie Flanagan has committed another €2.5 million in funding to the migration crisis in Europe.
Following a meeting this morning with EU Commissioner Chirstos Stylianides, Mr. Flanagan said his concerns had "increased" about those living under siege in Syria.
"There is an onus on all of the international community to do what we can to help alleviate this human suffering and Ireland will continue to play its part," Mr. Flanagan said.
Ireland has contributed over €55 million in humanitarian funding to the Syrian crisis since 2012. It is expected that funding to the crisis will reach in excess of €62 million in 2016.
The Minister also discussed the current status of the migration crisis, saying there is a need "to address the root causes of the crisis".
Earlier this week, the White House said it had suspended contact with the Kremlin over Syria.
Tense relations sharply deteriorated when the US State Department announced that bilateral discussions were being stopped.
The move had been threatened last week by Secretary of State John Kerry, furious at repeated airstrikes on rebel-held areas of Aleppo.
Hundreds of civilians are thought to have been killed in bombardments of the city in recent weeks, including a barrel-bomb attack on main hospital M10 in Aleppo.
