According to media reports, the airstrikes hit a residential area near the ministry of defence building, which had been targeted just before.
A number of houses were also reportedly damaged in the strike.
Yemen's Houthi rebels have claimed responsibility for firing the ballistic missile.
Yemen has been immersed in a violent conflict between President Abd Rabbuh Mansur Hadi's government and the Houthi Shia movement.
Since March 2015, the Saudi-led coalition of mostly Persian Gulf countries has been carrying out airstrikes against the Houthis at Hadi's request.
According to the UN, from March 2015 to March 2017, 16,200 people have been killed in Yemen, including 10,000 civilians. (ANI)
