The rockets hit Masa military camp in Yemen's west-central Ma'rib Province, killing and injuring a number of militants there, Saba news agency reported.
The attack against the Saudi-led forces came in retaliation for the continued massacre of civilians and destruction of Yemen’s infrastructure by the coalition led by Riyadh.
Yemen’s defenseless people have been under massive attacks by the coalition for more than three years but Riyadh has reached none of its objectives in Yemen so far.
Since March 2015, Saudi Arabia and some of its Arab allies have been carrying out deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive former president Abd Rabbuh Mansour Hadi, a close ally of Riyadh.
The Yemeni Ministry of Human Rights announced in a statement on March 25 that the war had left 600,000 civilians dead and injured until then. The war and the accompanying blockade have also caused famine across Yemen.
