The official Palestinian Wafa news agency didn't even cover the story of the assassination of Iranian defense official and nuclear scientist Mohsen Fakhrizadeh.
Wafa covers every phone call that Mahmoud Abbas makes or receives, but there was no statement by him or any other Palestinian official denouncing Fakhrizadeh's death or using it as a reason to paint Israel as a lawless aggressor, the way that Syria, Hezbollah, Hamas and others are.
The UN and even the EU issued a statement condemning the hit. Of course so did Hamas and Islamic Jihad.
The silence of the PLO is very interesting.
The reason seems to be that the PLO and Fatah are assuming that the US supported the hit. They do not want to make any waves before Joe Biden is sworn in as President; they certainly don't want to do anything to upset Trump between now and January 20 which can affect their relations with the US.
