Two people were killed in another round of intense shelling between Western-backed Ukrainian government's forces and pro-Russian fighters in the separatist east, officials from both sides said. Ukraine's military spokesman Andriy Lysenko said one soldier was killed and six wounded in the past 24 hours of fighting across the mostly Russian-speaking war zone.
