The rebel chief who led the overthrow of the longtime dictator Bashar al-Assad has been declared the head of government for a transitional period.

Syria's de facto leader Ahmed al-Sharaa was declared president for a transitional phase on Wednesday, tightening his hold on power less than two months after he led a campaign that toppled Bashar al-Assad.

He had spent the day with the leaders of Syria’s myriad armed factions, trying to persuade them to disband. Over seven weeks after the fall of Damascus, the fate of these groups is still uncertain. His aides claim that all militias will be dissolved and then absorbed into a new national army.
