ADDIS ABABA (Reuters) - The Ethiopia government on Thursday declared it would begin observing a truce with rebellious Tigrayan forces in order to allow aid into the war-ravaged northern province.

       More than 90 percent of 5.5 million Tigrayans need food aid, according to the United Nations, but only a tiny trickle has entered since Ethiopian troops withdrew from Tigray at the end of June last year.

       TPLF leaders were not immediately available for comment.
