The U.S. is to give more than $300 million in additional “life-saving humanitarian assistance” to Syrians caught up in the country’s civil war, Barack Obama has announced, taking the total amount given since the conflict began to nearly $815 million.
The extra money will be used to pay for food, medical care, clean water, shelter and other relief supplies for people in Syria and some of the 1.6 million refugees who have fled to neighboring countries.
The president announced the extra money during a meeting with world leaders at the Group of Eight summit in Lough Erne, Northern Ireland, on Monday.
