Sudan accuses Uganda of supporting and sheltering rebels fighting against the regime in Khartoum, while Uganda has in the past accused President Omar al Bashirs government of fighting a proxy war against it by sponsoring the Lords Resistance Army (LRA) rebels.
Uganda expected to recall its ambassador in Khartoum.
Recall means the end to an effort by a committee that was put in place by foreign affairs ministries of the two countries to try and calm the emerging diplomatic war.
