Yemen officially confirmed that Russia and North Korea have assisted the army to increase the range and precision-striking power of its missiles, Fars News reported.
"We have used (experiences) of the Russian and Korean experts to develop the range and precision-striking power of missiles," said Yemeni Army Spokesman Brig. Gen. Sharaf Luqman.
He added that the Borkan H2 ballistic missile that hit King Khalid airport in Riyadh was just a "warning shot."
"The missile hit the area outside the premises of King Khalid airport while the Yemeni army's missile unit could even target the airport's halls but it didn’t to prevent civilian casualties," Luqman said. "We will intensify our attacks if the Saudi enemy continues aggression against the Yemeni nation," he warned.
