An explosion outside a hotel in Ethiopia's volatile eastern region killed four people Sunday and injured 20 others, a federal police spokesman said, according to AP. The explosion occurred at 10:20 a.m. (0720GMT) outside a hotel in the eastern Ethiopia town of Jijiga, some 700 kilometers (435 miles) east of the capital, Addis Ababa, said spokesman Demsash Hailu. «It is a criminal act. It's not an accident. It was a terrorist action,» he said. The explosion killed or injured people in front of the hotel and on the street but did not damage the hotel itself, he said, declining to say what caused the explosion or who may have caused it.
