Yemen's Houthi forces said, they fired a ballistic missile on a Saudi border guards' base, in retaliation for air strikes by a Saudi-led coalition.
It said, the missile was fired late on Tuesday and hit the Saudi border guards' base in Najran, a city in south-western Saudi Arabia, near the border with Yemen.
"The missile came, in response to breaches to the ceasefire and continuing air strikes by the Saudi aggression," a military source of the Houthi group, said.
The Saudi government has yet to comment on the attack, but it's war planes appeared to response to the attack with several air raids on Wednesday morning, targeting Houthi military bases around the capital Sanaa, according to residents.
Houthis, who control most northern parts of Yemen, have launched ballistic missiles at Saudi Arabia several times since Saudi-led coalition forces engaged in Yemen's civil war more than a year ago.
Saudi forces have since shot down many rockets by patriot missiles, supplied by the United States.
Saudi Arabia led a coalition from mostly Arab countries, intervened in Yemen's conflict in 2015, to restore power to internationally recognised President Abd-Rabbu Mansour Hadi, after Houthis, backed by allied forces, stormed the capital Sanaa and forced Hadi with his government into exile in 2014.
