Syria's de facto leader Ahmed Al-Sharaa reached an agreement on Tuesday with former rebel faction chiefs to dissolve all groups and consolidate them under the defence ministry, according to a statement from the new administration.
Prime Minister Mohammed Al-Bashir had said last week that the ministry would be restructured using former rebel factions and officers who defected from Bashar Al-Assad's army.
Sharaa will face the daunting task of trying to avoid clashes between the myriad groups.
The country's new rulers appointed Murhaf Abu Qasra, a leading figure in the insurgency that toppled Bashar Al-Assad, as defence minister in the interim government.
Sharaa has told Western officials visiting him that the Hayat Tahrir al-Sham (HTS) group he heads, a former Al Qaeda affiliate, will neither seek revenge against the former regime nor repress any religious minority.
