Dozens of mercenaries fighting for the regime in Riyadh have been killed in a strike by a domestically-manufactured ballistic missile fired by Yemeni army forces on their base in the northwestern Yemeni province of Sa’ada near the border with the southern Saudi region of Najran.

AVA- Spokesman for the Yemeni Armed Forces Brigadier General Yahya Saree said a short-range and solid-propellant Badr P-1 missile hit al-Boqe'e base with great precision on Sunday evening, Yemeni Arabic-language al-Masirah television network reported.
The source added that the missile strike left at least 40 mercenaries dead and tens of others injured.
The Badr P-1 missile was unveiled during a ceremony in the Yemeni capital city of Sana’a on October 27 last year. It is said to have a pinpoint accuracy of three meters.
Earlier a number of mercenaries were killed and injured when Yemeni soldiers and allied fighters from Popular Committees detonated an explosive device in the Bir al-Basha area of Yemen's southwestern province of Ta'izz.
Separately, Saudi military aircraft launched a series of airstrikes against residential buildings in the Nihm district of Sana'a province, leaving three women and an elderly man dead. A man suffered injuries as well.
Saudi Arabia and a number of its regional allies launched a devastating campaign against Yemen in March 2015, with the aim of bringing Hadi’s government back to power and crushing the Houthi Ansarullah movement.
According to a new report by the Armed Conflict Location and Event Data Project (ACLED), a nonprofit conflict-research organization, the Saudi-led war has so far claimed the lives of about 56,000 Yemenis.
