Arab alliance jets shelled Houthi and Saleh militias in Sanaa last night.
More than 10 bombings were heard inside al Nahdin Mountain camp, eyewitnesses said.
The jets also targeted sites near the presidential palace.
The Saudi-led intervention in Yemen began in 2015 to influence the outcome of the Yemeni civil war. Saudi Arabia, spearheading a coalition of nine Arab countries, began carrying out airstrikes in neighboring Yemen and imposing an aerial and naval blockade on 26 March last year.
