HaaretzPalestinian mission in Washington granted title of 'general delegation' and given permission to hang PLO flag at entrance.<

"The U.S. announced this week that it would upgrade its diplomatic relations with the PA by granting its mission in Washington - which is actually a PLO mission - the same status it enjoys in most European countries: that of a PLO "general delegation."
This is still a lower status than an embassy - a status the PA mission does have in many African and Asian countries, as well as some European and South American states. But it is a major step above what the PA has had until now.
Prior to this decision, the PA mission in Washington was at a very low level from the point of view of protocol: Its diplomats did not have diplomatic immunity, and it was not even allowed to fly the PLO flag at the entrance to its offices.
Now, its diplomats will enjoy diplomatic immunity and its offices will be able to display the PLO flag."
