Palestinian siblings Dia Awaja, right, 4, and Zikrayat, 2, left, play on one of the tents which comprise the makeshift structures that house their family, in Beit Lahiya, northern Gaza Strip, Thursday, June 10, 2010. The Awajas are among thousands of families whose houses were destroyed during Israel's three-week military offensive against Hamas-ruled Gaza, launched in December 2008 with the aim of halting Hamas rocket attacks. An Israeli forces bulldozer flattened the Awajas' house and as the family tried to flee, bullets the siblings father Kamal, mother Wafa, and their 8-year-old brother Ibrahim, who bled to death in the street.
