A Yemeni young man was killed and four others were injured on Tuesday in an explosion of a hand grenade in the capital Sanaa.
The bomb is a remnant of the clashes that took place in September between Houthis and the regime forces in Sanaa, which left 274 people dead.
In a statement, the Yemeni interior ministry said that the five found the bomb and tried to examine it before it went off, leaving one dead and four severely injured.
