The UN Relief and Works Agency has said there are around 500,000 Palestinians living in Syria, many of whom fled their homeland due to the decades-old territorial dispute with Israel.
The UN says 1,000 Palestinians left their homes in Syria in July, and that number has risen now to 3,000 as fighting intensifies in the capital.
Many Palestinians caught in the Syrian crossfire are fleeing across the border to Lebanon, a country already home to more than 400,000 Palestinian refugees where the newcomers feel unwelcome.
