ROUCH CUT (No reporter narration)
At least 47 people were killed, including four children, when a suicide bomber detonated a belt packed with explosives at a Houthi checkpoint in the centre of the capital Sanaa where Houthi supporters were preparing to hold a rally on Thursday.
Body parts were scattered across Tahrir Square and pools of blood formed on the asphalt after the blast.
The explosion was captured by a closed circuit televison camera attached to a wall of the Yemen Bank for Reconstruction and Development.
In addition to those killed, more than 75 others were injured in the attack.
No group has claimed responsibility.
