The five-year long fighting between government forces and Houthi fighters in the north of Yemen has cast a shadow on the future of this Arab country.
Houthi fighters, who are Zaidi Shia Muslims, are seeking independence from a government which they say is corrupt and too close to Saudi Arabia.
The latest round of fighting started in Yemen's north last month and has continued primarily in Saada province.
It is estimated that more than 100,000 people have been displaced in the fighting in Saada and UN aid agencies are warning that Yemen is on the brink of a humanitarian crisis.
Just four hours after a truce was declared on Saturday, fighting had resumed with both sides claiming the other had broken the ceasefire.
Is Yemen heading for another civil war? And how are regional powers influencing events in a country considered a breeding ground for extremist groups?
