The artillery units of the Yemeni army and popular committees hit Saudi several military bases in Jizan, including al-Mahrooq, the Arabic-language al-Masirah television network reported on Thursday.

The units also targeted supply lines to the Saudi military forces in the border province, according to the report.

The attacks came after Saudi warplanes recently targeted civilian areas in Yemen’s northwestern Sa’ada province, killing and injuring several people.

Since March 2015, Saudi Arabia and some of its Arab allies have been launching deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.

According to UN estimates, over 10,000 Yemenis, including 4,000 women and children, have lost their lives in the military campaign.
