Scores of Yemeni troops, including leaders, were killed or injured on Thursday when a bomb-laden drone targeted the Anad Military Base in the southern governorate of Lahj, with attack claimed by Houthi group.
A blast took place in Anad camp while hosting a military parade, Yemeni sources said noting that initial reports say among injuries were Chief of Staff Abdullah al-Nakhie, his deputy Saleh al-Zyndani, head of intelligence Mohammed Saleh Tamah, commander of Anad front Thabit Jawas and commander of Fourth Military Region Fadhl Hassan.
Later, an official at the internationally recognized government stated that Chief of Staff al-Nakhie, his deputy al-Zyndani and Lahj Governor General Ahmed al-Turki were slightly wounded at the explosion.
"Four troops, including an officer, were killed and ten others injured," he added "in initial toll."
Houthi group immediately claimed the attack on the Anad Airbase, according to the rebel mouthpiece al-Masirah TV.
Houthi-run, Sana'a-based Saba stated that a number of military leaders were killed and injured in the airstrike.
Based in al-Anad District of the southern governorate of Lahj, Anad Base is one of most vital and the largest military bases.
A drone approached the military leadership podium at the base, said a local source. "We had thought it was filming the military ceremony, before it exploded near the podium."
Casualties were taken to hospitals in Aden and Lahj cities, he added.
Yemen has been racked by an armed conflict that broke out after the Iran-backed Houthis had ousted the internationally recognized government late in 2014.
The conflict escalated after a Saudi-led coalition intervened militarily in the country in March 2015 to reinstate the government of President Hadi, leaving tens of thousands killed, hundreds of thousands injured, and 3 million displaced.
The war has pushed the country to the world's worst humanitarian crisis, according to the UN, with more than two thirds of the 28-million population in need for a type of humanitarian aid and immediate protection, including 8.4 million people unsure how to get next meal, and some 2 million children suffering severe shortage of nutrition.
