A Palestinian youth pushes a bicycle past the rubble of the former house of Fatah strongman Mohammed Dahlan after it was hit in an Israeli missile strike in Gaza City, Monday, Jan. 12, 2009. Israeli warplanes pounded the homes of Hamas leaders in the Gaza Strip and ground troops edged ever closer to the territory's densely-populated urban center Monday but reported casualties were low, an indication that Hamas was largely avoiding pitched battles with the advancing Israelis.
