The first photo is an AP photo bearing the caption:
A Palestinian carries a child into the Shifa hospital in Gaza City, wounded during the Israeli army operation in Gaza, Sunday Jan. 4, 2009. Israeli ground troops and tanks cut swaths through the Gaza Strip Sunday, bisecting the coastal territory and surrounding its biggest city as the new phase of a devastating offensive against the Hamas group gained momentum.
I cropped the second (Getty) photo to the same size as the other (before combining them in one image). The second caption is:
A Palestinian father carries his wounded baby daughter into a hospital in Gaza City on January 4, 2009 as Israeli troops continue its ground assault in Gaza. The half dozen hospitals in Gaza cannot cope with more patients and casualties are overflowing out of regular wards into corridors as Israeli troops push deep into Gaza. At least 40 people have been killed since Israel launched the night-time offensive yesterday after eight days of air strikes in which at least 485 Palestinians died and more than 2,400 were wounded, Gaza medics said.
Obviously, it is the same baby; the burn mark on the forehead is the same. Even if the face wasn't visible, the orange and green clothing would be suspect. Perhaps the second photo wasn't staged, but I'm not sure why a different man would be carrying the same (undressed) baby into another hospital. It sickens me that such a badly injured child is no more than propaganda to these people.
