There is no doubt about that. He has admitted it.
While newspapers say that he denied having anything to do with a plot to assassinate Israel's Sephardic chief rabbi, and that he was even a member of the PFLP, he admitted to the plot in his plea bargain. Moreover, he essentially admitted to and justified the plot in this PFLP website, no longer online, from 2011, which also calls him a member of the group ("comrade.")
Moreover, this PFLP website listed him as one of their members, #8, who participated in a hunger strike only this past September (autotranslated):
But this would-be assassin is labeled a "human rights defender" by the UN, by the International Federation of Human Rights, and Amnesty International.
Which can only mean one of two things. Either these "human rights" organizations consider murdering Jewish Israelis to be a human right, or they don't believe that Jews in Israel are human to begin with.
Either way, calling Hammouri a "human rights defender" proves that the term "human rights" has lost all meaning, and indeed means the opposite of its original definition.
In this, they agree with the PFLP itself, which makes that equation between murdering Jews and "human rights' explicit, as one of their officials said ten years ago:
We reaffirm our commitment to our goals, principles, and inalienable Palestinian national rights. Some of which have been recognized and approved by international norms, principles, agreements, resolutions, international law and human rights. The first of these rights is the right of the Palestinian people to resist the occupation by all means and methods.
Every Palestinian understands "all means and methods" to include terrorism against civilians.
"Human rights organizations'" defense of Hammouri indicates that they agree.
