Palestinian rivals Hamas and Fatah are trading some of the harshest accusations in months, raising new doubt about their ability to work together to rebuild areas of the Gaza Strip destroyed in last summer's Israel-Hamas war.

Gaza's ruling Hamas claims the Fatah-run self-rule government in the West Bank ordered supporters to carry out bombings in Gaza to create chaos. Over the weekend, Hamas released videos purportedly showing confessions of three men involved in the alleged plot.

Gaza Interior Ministry spokesman Iyad Bozum also claims Fatah ordered supporters in Gaza to relay information about Hamas' military infrastructure.

Adnan Damiri, a spokesman for Fatah-loyal troops in the West Bank, alleged Sunday that the videos are forged. He says Hamas is trying to distract from its failure of governing Gaza.
