After UN vote
Apparently, Fatah is thanking the 14 countries because they interpret their UN vote as granting Fatah permission to kill Israelis.
The 14 countries thanked by Fatah are:
Russia, Angola, Ukraine, Japan, Spain, Egypt, Malaysia, Venezuela, New Zealand, Senegal, Uruguay, France, China, and Britain.
The United States, whose abstention actually enabled the resolution to pass, is not mentioned.
