An improvised bomb exploded outside the republican palace in the center of Yemeni capital Sanaa on Saturday and wounded three Shi'ite Muslim militiamen guarding it, eyewitnesses said.
The attack came a day after the Houthi Shi'ite militant group dissolved parliament and formally took power of the impoverished and strife-town Arabian state.
Once the home of the resigned Yemeni prime minister, the republican palace now houses Mohammed Houthi, a top official in the movement's military wing whose gunmen now hold sway over much of Yemen.
