Protests over high fuel prices in Ireland have entered a fourth day, sparking concerns about fuel shortages and emergency services as demonstrators clogged roads and blocked access to refining and distribution sites around the country. The Irish government is set to meet with farmers, truckers and agricultural contractors on Friday to discuss the crisis, triggered by rising gasoline and diesel costs as the conflict in the Middle East restricts oil exports from the region. While organizers have said they will call off the coordinated protests if the government agrees to talk with them, it is unclear whether they will be included in the talks.
