Two Houthi followers were killed and five others injured when an unknown person detonated a bomb at the protest square in Yemen's Saada province on Monday.
The bomb exploded when a massive demonstration organized by the Houthi Group started coinciding with massive demonstrations in other Yemeni cities to condemn the crimes of the remaining officials of the Saleh regime and the regional and international collusion with them.
Newsyemen.net quoted locals in Saada that Houthi security committees prevented a man from entering the square and the man then threw the bomb at protesters.
In other cities including the capital Sana'a and Taiz, hundreds of thousands took to the streets to condemn the crimes of the Saleh regime and the regional and international collusion with it.
They also urged a final revolutionary action as they rejected the U.S. and Saudi positions towards the popular youth-led uprising in Yemen.
Furthermore, they condemned the collective punishment of the Yemeni people through creating the acute fuel crisis and price hikes, saying the remaining officials within the Saleh regime are waging a dirty starvation war in the country.
They chanted slogans such as: the regime is behind crises and is killing the people.
