On 17 April 2008, the FLN bombarded Bujumbura. The Burundian army fought back and the FLN suffered heavy losses. A new ceasefire was signed on 26 May 2008. In August 2008, President Nkurunziza met with the FLN leader Agathon Rwasa, with the mediation of Charles Nqakula, South Africa's Minister for Safety and Security. This was the first direct meeting since June 2007. Both agreed to meet twice a week to establish a commission to resolve any disputes that might arise during the peace negotiations.
