COLOMBO – Sri Lanka reopened to foreign tourists Thursday after a nearly 10-month pandemic closure that cut deeply into the Indian Ocean island nation's lucrative travel industry.Full operations also resumed Thursday at the island's two international airports, accommodating the commercial flights.Under new protocols to prevent the spread of COVID-19, tourists must be tested for the virus in their country 72 hours prior to their flight, when they arrive at their hotel in Sri Lanka and again seven days later.
