AlQa'dah 7, 1434, Sep 13, 2013, SPA -- The U.N. humanitarian chief Friday allocated $50 million to support the efforts of humanitarian agencies assisting the growing number of Syrians affected by the two-and-a-half-year crisis in the country and in the region. Valerie Amos said that the money from the U.N. Central Emergency Response Fund represents the largest-ever single contribution to support a coordinated response to a single crisis. Amos said that $20 million will support aid operations inside Syria, $15 million will go to scale up efforts in Lebanon, $10 million will support the recent influx of Syrian refugees in Iraq, and $5 million will boost humanitarian programs in Jordan. The United Nations says that more than 4.2 million people are displaced within Syria and 2 million have fled to other countries in the region.
