The Houthis, who are demanding that the government resign and subsidies be fully restored, have been fighting for years for more power for their Zaydi Shia sect in northern Yemen.
Now they have moved to the capital Sanaa, threatening to block roads and occupy government buildings to achieve their goals.
As the turmoil in Yemen intensifies, president Abd Rabbu Mansour Hadi has accused Iran of interfering in his country's internal affairs - an accusation Tehran denies, with a foreign ministry spokeswoman saying Iran supports unity, security and stability in Yemen.
Also, the current unrest throws efforts for a peaceful transition in doubt.
So, is Yemen headed for a conflict? And is the current government able to deal with it?
