Khartoum: Sudan's military and opposition groups have agreed to resume talks on the formation of a transitional council, an Ethiopian envoy said on Tuesday, as an opposition alliance said it was suspending its campaign of civil disobedience and strikes.

Sudan's Transitional Military Council also agreed to release political prisoners as a confidence-building measure, special envoy Mahmoud Dirir told reporters in Khartoum.

The steps appeared to show a softening of positions after talks between the two sides collapsed following the violent dispersal of a protest sit-in on June 3.

The crackdown, in which dozens of people were killed, dealt a big setback to hopes of a transition towards democratic elections following the overthrow of veteran leader Omar al-Bashir in April.
