Three northeastern provinces of Syria face an "alarming" food crisis, although access to relieve the impact of civil war has improved somewhat elsewhere, a U.N. aid agency said on Monday. Days before the Syrian conflict enters its fourth year, the World Food Programme (WFP) said the hardest areas to reach were the northeastern provinces of Raqqa, Deir al-Zor and Hassaka. "We don't have total absolute numbers on deaths due to starvation. There are no massive indications of that. But there are certainly widespread (and) what I would call alarming nutritional indicators," Amir Abdulla, the U.N. agency's deputy executive director, told a news briefing in Geneva.
