Lebanon's central bank has tightened controls on withdrawals from dollar accounts by suspending a special exchange rate that aimed to ease a foreign currency shortage. The move wiped more than half the value off dollar deposits in Lebanese banks. The country's hospitals are also suffering from the dollar shortage, as the state cannot pay for imported medicines. A political deadlock has exacerbated the crisis, which the World Bank has described as among the worst the world has seen in 150 years.
