The Nordic region’s top telecom operator, Swedish-Finnish TeliaSonera , said on Monday it reached a deal to buy US-based MCT Corp., which has stakes in mobile operators in Uzbekistan, Tajikistan and Afghanistan.

The firm said in a statement the transaction is expected to close by the third quarter.
