COLOMBO, Sri Lanka (AP) — Senior U.S. officials are in Sri Lanka seeking ways to help the island nation cope with an unprecedented economic crisis and severe shortages of essential supplies. The energy minister warned in a tweet that new fuel shipments would be delayed and people shouldn’t be lining up at pump stations. The U.S. has announced millions of dollars in assistance to Sri Lanka, which has been surviving on $4 billion in credit lines from neighboring India. It also has received pledges of $300 million to $600 million from the World Bank to buy medicine and other items. Prime Minister Ranil Wickremesinghe last week announced the economy had “collapsed” due to dwindling foreign exchange reserves and a mounting debt.
