Al-Jazeera Video: Palestinian refugees escape Syria violence

"The UN Relief and Works Agency have said there are around half a million Palestinians in Syria - who over the decades fled wars involving Israel.

It says 1,000 left their homes in July, but that number has risen now to 3,000 as fighting intensifies in the capital. As fighting continues in Syria many Palestinian refugees caught in the crossfire are fleeing across the border to Lebanon.

However, they are largely unwanted in Lebanon, which itself is already home to more than 400,000 Palestinian refugees.
