Aceh – Nanggroe Aceh Darussalam Special Detachment anti-terror squad (Densus 88) will investigate the bombing of former Free Aceh Movement (GAM) leader Muzakkir Manaf's residence in Aceh.

"We are still investigating and checking the type of grenade used," Densus 88 head Sutry Hamdani told Antara in Aceh Besar on Tuesday.

An unidentified person reportedly bombed the house of Muzakkir Manaf, who is also the chairman of the Aceh Party, early Tuesday morning. The attack left Manaf's front window broken and damaged his car, a Nissan X-Trail.

A witness, Tarmizi, said Manaf and his family were in Lhokseumawe, 270-kilometer away from Aceh, at the time of the attack.

Aceh Party spokesman Adnan Beuransah said he did not know of any frictions rising between the party and other parties.

"We truly regret the attack as it shows there are certain individuals unhappy with peace. We will report the incident to the regional police, Interpeace, European Union and the Communication and Coordination Forum (FKK)," he said. (amr)
