From Ynet News, 29 July 2013, by AFP:
A major faction of the Palestine Liberation Organization rejected new peace talks with Israel just hours before their scheduled resumption in Washington on Monday after a three-year break.
The leftist Popular Front for the Liberation of Palestine said that talks' resumption was a unilateral move by Palestinian leader Mahmoud Abbas which did not have the backing of the PLO as a whole.
"The PFLP is against a return to negotiations," said one of the party's leaders, Khaleda Jarar. "It is an individual move," she said, in allusion to Abbas. ..."We went to the UN precisely to take our case out of US hands."
...Washington was to host preliminary talks later on Monday between Palestinian chief negotiator Saeb Erakat and his Israeli counterpart, Justice Minister Tzipi Livni .
The last round of direct negotiations between the two sides broke down in September 2010 just weeks after they started.
US Secretary of State John Kerry visited the region six times in as many months to broker the resumption of negotiations.
