In a Q&A published by non-governmental think tank International Crisis Group (ICG) on Friday, the Horn of Africa director said there is not yet ‘‘a clear path out’’ of Sudan’s political impasse but ‘‘progress remains possible.’’According to ICG’s Alan Boswell, the resilience of Sudan’s protest movement since October’s coup, along with Abdelfattah El Burhan’s apparent willingness to allow civilians to form a government, could facilitate progress.
