PA officials were quick to blame Hamas.
But the Hamas newspaper Felesteen says it was Israel.
Professor Yousef Rizqa declares that assassinations are a "Jewish industry." He notes that the Mossad likes to assassinate anti-Zionists all the time, so therefore they must have been behind this attempt, since the only beneficiary to such a murder would be Israel.
Also, he says, Hamas' security services are excellent and they would thwart any such attempt from anyone in Gaza. Israel has more resources, Rizqa implies, and therefore only Israel could have planted the IED.
He fails to note that if Israel wanted to assassinate Hamdallah - he'd be dead.
Rizqa's CV at the University of Gaza says he's been an advisor to the "prime minister" - meaning Hamas' version of prime minister - since 2007.
