The second programme exploring the lives of Palestinian refugees, this Life episode is set in Lebanon, where - according to the UN - there are 375,000 Palestinian refugees. Palestinians are unwanted in Israel, as we saw last week's programme; but in war-torn, sectarian Lebanon, among fellow Arabs, they hardly fare better, and most live in poverty. Barred from working, they also have limited access to medical care and higher education. Many have been in Lebanon for 50 years.
