YEREVAN. – Armenian parliament's non-ruling factions decided to boycott a special session on Monday, secretary of Heritage party Ruben Hakobyan said.

He said it is impossible to discuss current problems, until an assault on their counterpart Aram Manukyan is not investigated.

“My colleagues from Heritage Party, Orinats Yerkir, Prosperous Armenia and Armenian National Congress are boycotting the session,” he said.

Following his statement, deputies of four parliamentary groups left the hall. ARF Dashnaktsutyun lawmakers stayed in the hall, but decided to leave in 10 minutes.

As reported earlier, an unidentified person assaulted and hit Aram Manukyan, an MP from the Armenian National Congress, in the entrance of the building where he lives. In addition, several days ago Karabakh war veterans Razmik Petrosyan, Manvel Yeghiazaryan and Suren Sargsyan were beaten.
