A supporter of the Shi'ite al-Houthi group looks on as he takes part in a demonstration in Yemen's capital Sanaa June 4, 2014. A ceasefire between Shi'ite Muslim rebels and government forces went into effect on Wednesday, the Yemeni Defence Ministry said, after fresh fighting and air strikes killed a total of 19 people from both sides. Nearly 140 people have died in three days of fighting near the town of Omran, where government forces and allied Sunni Muslim tribesmen have been trying to hold back the powerful rebel militia from capturing the city for nearly two months. The sign reads: "Allah is the greatest. Death to America, death to Israel, a curse on the Jews, victory to Islam." REUTERS/Khaled Abdullah (YEMEN - Tags: POLITICS CIVIL UNREST TPX IMAGES OF THE DAY)
