SANAA (AFP) - Yemeni Nobel peace laureate Tawakkul Karman warned in an interview with AFP that her country’s transition process is on the brink of collapse and demanded ex-president Ali Abdullah Saleh be banned from politics. The activist, who was a leading figure during the youth uprising in Yemen in 2011, also claimed that President Abdrabuh Mansur Hadi is unable to implement his plans to reshape Yemen’s security forces because he does not control the army. “The main obstacle facing the political transition and threatening its viability is the fact that Ali Abdullah Saleh remains a president of the General People’s Congress,” the former ruling party, Karman said.
