A third day of renewed peace talks between Sudan's government and rebels from the war-torn Darfur region is planned for Wednesday in Abuja, Nigeria.
There have been no reports of progress since a new round of talks opened Monday in the Nigerian capital. Tuesday's talks broke off shortly after they began.
Rebels are demanding that a security deal is reached before they agree to sign a humanitarian protocol that could help protect more than 1.5 million displaced villagers in the Darfur region. Tens of thousands of people have been killed since the Darfur conflict began early last year.
Pro-government Arab militias have been accused of atrocities against black Sudanese villagers in Darfur. The government and rebels accuse each other of breaking a ceasefire agreement in the region.
