Ireland announced some of Europe’s toughest COVID-19 constraints on Monday, shutting non-essential retail, limiting restaurants and pubs to take away service and telling people not to travel more than five kilometers (3 miles) from their home.Ireland imposed one of Europe’s longest lockdowns during the first surge in coronavirus cases and eased restrictions at such a cautious pace that pubs that only serve drinks in Dublin had not reopened by the time a rise in infections prompted a tightening of curbs.This time, schools will stay open and essential services such as construction are allowed to continue, Prime Minister Micheal Martin said, as he moved the country to the highest level of restrictions, Level 5, for six weeks from midnight.
