An estimated 120,000 refugees have returned home since coming here July 14, the refugee agency said.
Two Palestinian employees of the refugee agency have also been killed.
The refugee agency has witnessed other violence in the past year.
Only nine of the refugee agency's 364 professionals are Japanese.
Most of the refugee agencies here have no plans to disseminate that information.
At the same time, the protection division of the refugee agency has been diminished.
But holding back the refugees is against international law and the mandate of the refugee agency.
The refugee agency has used mass communications campaigns in similar efforts.
It is also one of the refugee agency's toughest challenges.
For three months the government and the refugee agency tried to negotiate with a small group of leaders.
