Houthi fighters in Yemen say Saudi fighter jets are using phosphorous bombs to back a deadly Yemeni government offensive against them.
"Saudi combat fighter jets launched intense raids against border areas inside Yemeni territory on Sunday night," the fighters' spokesman Mohammad Abdessalam told AFP by telephone.
"The Saudi military used phosphorus bombs during those night raids, burning mountainous regions," he said adding that "The Saudi air raids resumed this morning (Monday). "
Abdessalam said that the raids targeted Malaheez, seven kilometers (3.8 miles) inside Yemen, as well as the border villages of Hassameh and Shida and several villages around Jebel (mountain) al-Dukhan straddling the border.
