The missile and artillery unit of the Yemeni army and popular committees targeted positions and military equipment of Saudi troops in Najran in southern Saudi Arabia, inflicting heavy casualties on them.
Islamic Republic News Agency (IRNA) quoted Almasirah news network as saying that a garrison and military base of Saudi Arabia were hit in the attack.
On Tuesday, the Yemeni forces targeted Jaba al-Dud region and established control over it.
Since March 2015, Saudi Arabia and some of its Arab allies have been carrying out deadly, indiscriminate airstrikes on civilians in an attempt to restore power to fugitive president, Abd-Rabbuh Mansur Hadi, a close ally of Riyadh.
Over 14,000 Yemenis, including thousands of women and children, have lost their lives in the deadly Saudi aggression.
