Afghanistan has begun disbanding private security companies operating in the country, shutting down eight firms and seizing over 400 weapons, the Interior Ministry said on Sunday. The move is part of President Hamid Karzai's ambitious plan to take over all Afghan security responsibilities from foreign troops by 2014. Since Karzai's decree in August, a plan has been drawn up for the process which is expected to be complete by the end of the year, Interior Ministry spokesman Zemarai Bashary said. The United Nations and Nato-led International Security Assistance force had given it their support, he added. The interior ministry is implementing this plan with seriousness and decisiveness, he told a regular briefing.
