Police in Kosovo have arrested six people in connection with the firing of a rocket-propelled grenade at the parliament building earlier in August that was claimed by a hard-line nationalist group.
The suspects are all members of the opposition Vetevendosje party.
Vetevendosje lawmakers have released teargas in parliament several times during the past year while their supporters have clashed with police outside.
The hard-liners oppose a border deal with Montenegro and an EU-brokered accord with Serbia that would give more autonomy to Serb-held areas of Kosovo.
Both of the deals are essential for Kosovo to build closer ties with the European Union.
While making the arrests on August 30, police said they recovered three automatic rifles, two pistols, and a rifle with a telescopic sight.
The attack on parliament was carried out on August 4 by two motorcyclists who fired a rocket-propelled grenade as they drove past.
The parliament building was damaged but no one was hurt.
