The Houthi Group (Ansar Allah) said on Tuesday, it fired a medium-range ballistic missile at gatherings of the Saudi army and their so-called "deceived" in Najran, southwest of the kingdom.
The military spokesman for the Houthi forces, Brigadier General Yahya Saree, said in a statement that the group's missile force fired a medium-range ballistic missile, a "Qassim" type, against Saudi army and "deceived" in Saqam, referring to Yemen's internationally recognized government forces.
Neither Saudi Arabia nor Saudi-led military coalition has commented on Houthi claims yet.
Yahya Saree said: "Qassim is a new missile entered into service a while ago has proved its effectiveness significantly.
"Details about Qassim missile will be revealed later in a press conference", he added.
Saree stressed that "The enemy was preparing to march towards the positions of the army and the Popular Committees at the border,".
Since mid-May 2019, Houthis have intensified firing ballistic missiles and launching drone attacks on Saudi territory "in reply to coalition airstrikes that target Yemeni civilians and infrastructure."
Yemen has been devastated by a five-year armed conflict between the government backed a Saudi-led coalition and the Iran-backed Houthis who are still controlling most of the most densely populated regions in the north.
