20 dead in overnight clashes in north Yemen: tribal official

SANAA, July 22, 2010 (AFP) - Fighting overnight between Shiite rebels and army-backed tribes in northern Yemen killed 20 people on both sides, a tribal official told AFP on Thursday.

"Violent clashes took place overnight between Huthis and Bin Aziz tribes... leaving 20 dead from both sides," the official said.

Yemeni forces deployed in the area intervened to break up the fighting, he added.

Fighting in the mountainous north between the two sides over the past four days had left at least 49 people dead, threatening a fragile truce, tribal and rebel sources had said on Wednesday.
