Houthi rebels on Thursday fired a "ballistic missile" at a military camp in Yemen's Maarib province east of capital Sanaa, according to a Yemeni military source.
The source, speaking anonymously due to restrictions on speaking to media, said the missile had targeted eastern Maarib's Al-Ruweik military camp.
Ali Mohsen al-Ahmar, vice president of Yemen's internationally recognized government (now based in the port city of Aden), had been visiting the camp -- along with several Yemeni military officials -- at the time of the attack, the source said.
According to the same source, the missile fell to earth close to the camp without exploding or causing casualties.
Earlier Thursday, Houthi spokesmen appeared to confirm the missile launch, according to Yemen's Houthi-run Saba News Agency.
Anadolu Agency has yet to independently verify the claims.
Yemen has remained dogged by violence since 2014, when the Shia Houthis overran much of the country, including capital Sanaa, which they have retained until today.
In 2015, Saudi Arabia and its Sunni-Arab allies launched a wide-ranging military campaign aimed at reversing Houthi gains and shoring up Yemen's pro-Saudi government.
