The ANO has been especially noted for its uncompromising stance on negotiation with Israel, treating anything less than all-out military struggle against Israel as treachery. This led the group to perform numerous attacks against the PLO, which had made clear it accepted a negotiated solution to the conflict. Fatah-RC is believed to have assassinated PLO deputy chief Abu Iyad and PLO security chief Abul Hul in Tunis in January 1991. It assassinated a Jordanian diplomat in Lebanon in January 1994 and has been linked to the killing of the PLO representative there. Noted PLO moderate Issam Sartawi was killed by the Fatah-RC in 1983. In the late 1970s, the group also made a failed assassination attempt on the present Palestinian president and PLO chairman, Mahmoud Abbas. These attacks, and numerous others, led to the PLO issuing a death sentence "in absentia" against Abu Nidal. In the early 1990s, it made an attempt to gain control of a refugee camp in Lebanon, but this was thwarted by PLO organizations.
