"The Saudi Air Defense Forces managed to intercept a ballistic missile, this evening ..."
Local Yemeni news outlets cited a number of Saudi Twitter activists tweeting in Arabic language.
The Yemeni army says so far more than 100 ballistic missiles of various types have been fired at positions held by Saudi invaders inside and outside Yemen.
We have heard a sound that terrified residents in Riyadh, another columnist wrote.
The Trump administration is also considering stepping up intelligence support for the Saudi-led monarchs' coalition in Yemen, reversing a policy by ex-President Barack Obama who curbed the US role due to widespread civilian deaths and a seeming disregard by royals for basic humanitarian norms.
According to official Saudi news agency, the missile targeted an unpopulated area in south of capital Riyadh causing no casualties.
In the same context, the Yemeni capital of Sanaa has been witnessing intensive buzzing for about an hour, as Saudi Air Force launched intensive raids on missile bases in Attan mountain near Presidential Palace of Sanaa.
The incident on Friday occurred a day before US President Donald Trump was expected in Riyadh at the start of his first foreign trip since taking office in January.
Almost 3.3 million Yemenis, including 2.1 million children, are now suffering from acute malnutrition, while more than seven million people are grappling with starvation. The move would mark a significant reversal in policy from former President Barack Obama, who curbed the US' role in the Yemeni conflict as civilian deaths began to spike.
