A Palestinian boy plays near a building that was destroyed during Israel's January offensive in Gaza, in Jabaliya, northern Gaza Strip, Monday, Nov. 9, 2009. Senior U.N. official Maxwell Gaylard on Monday called on Israel to allow building materials into Gaza, warning that thousands of people displaced by an Israeli military offensive early this year face the prospect of a cold, rainy winter without a proper roof over their heads.
