Palestinians in Gaza and the West Bank have been ruled separately since a rift between Hamas and Mr Abbas's Fatah faction erupted in violence in 2007. It promised an "urgent" investigation.
A statement on official Palestinian media said Palestinian Authority President Mahmoud Abbas considered it a "cowardly targeting" of Hamdallah's convoy and held Hamas responsible.
