TRIPOLI, Libya - At least two people were killed in the western Libyan city of Tarhouna after gunmen ransacked a home in search of a regime figure once loyal to Moammar Gadhafi, a city resident said.

Basem al-Tarhoni said angry Tarhouna residents retaliated by torching the headquarters of about 100 fighters who helped topple the longtime leader from power.

Tarhouna was widely seen as a Gadhafi favorite, and its dominant tribe, which is also called Tarhouna, held many positions in the Libyan military. Its residents are viewed with suspicion by former rebels.

Such clashes are a major challenge for Libya's new rulers. The clashes occurred on the same day that security ministers announced a program for integrating former rebels in civil institutions.
