An explosion hit a bus carrying Yemeni soldiers in the capital Sanaa on Tuesday causing several casualties, a police source and witnesses said, Reuters reported.
The police source said eight people had been wounded, three of whom were in critical condition.
Yemen has been hit by turmoil since mass protests in 2011 eventually forced out long-serving President Ali Abdullah Saleh. The country, which neighbors Saudi Arabia and is home to one of al Qaeda's most active branches, is wrestling with instability, internal conflicts and poor governance.
