DUBAI - Shiite rebels in northern Yemen on Thursday claimed Saudi jets were bombarding their positions near the shared border.
"Saudi jets carried out several raids on Wednesday in Yemeni territory and continued their bombardment this morning," rebel spokesman Mohammed Abdessalam said in Dubai by telephone.
Saudi fighter planes targeted Jebel al-Dukhan, a mountainous region along the border and several other border areas, he said.
In a statement on Wednesday, the rebels said the Saudi army "had used phosphorous bombs" in its air raids on northern Yemen and accused Riyadh of intervention in Yemen.
Their allegations could not be independently verified.
The claims come after Riyadh said a border guard was killed and 11 others wounded when armed infiltrators attacked them inside Saudi territory in Jabal al-Dukhan.
It is not the first time Zaidi rebels, also known as Huthis, accuse Saudi Arabia of aiding the Yemeni army, which launched an all-out offensive on the rebels' stronghold in the Saada region on August 11.
Last month they accused the Saudi forces of firing across the border.
Riyadh has denied the charges.
The Sanaa government accuses Shiite Iran of backing the rebels. It announced last week the seizure of five Iranians on a boat loaded with arms in the Red Sea that it said was destined to the rebels.
Hundreds of people have been killed or wounded in the ongoing clashes, and tens of thousands forced to flee their homes, resulting in a humanitarian crisis complicated by a dire shortage of food and other basic necessities.
