Analysis: The race between the Houthis and the Arab coalition to secure control of Aden is on. The winner will secure a valuable card in the game to control Yemen.
The Houthi movement looks increasingly isolated after Hadi fled Sanaa for Aden and is receiving foreign delegations in Aden in his capacity as president of Yemen.
Al-Qaeda is using the political turmoil in Yemen and the redeployment of popular militias from areas of the south to attack government forces across the region.
As turmoil engulfs Yemen, the secessionist ambitions of the South received a boost from an unlikely source, President Hadi himself, says Faris al-Jalal.
Separatist sentiments are at fever pitch this week, as the Houthis take over vital government institutions and President Hadi resigned. The prospect of the south separating from the north is becoming a likely end to Yemen's political crisis.
When the two Yemens reunified in 1990, few would expect that a little over two decades later, calls for separation would be back in the political debate.
