CAIRO (Reuters) - Warring parties in Yemen reached a preliminary agreement on Tuesday to release all prisoners beginning within 20 days, sources at U.N.-backed peace talks in Kuwait said.
The agreement is one of the most important milestones yet in nearly three weeks of negotiations that have in recent days struggled to maintain a ceasefire on the ground and appeared headed for collapse.
A Saudi-led coalition intervened in Yemen's conflict a year ago, mainly with air strikes in support of the country's internationally-recognized government.
A tentative U.N-backed ceasefire has been in place since last month to give the peace talks in Kuwait a chance, but both sides have regularly accused each other of violations.
