The move is the latest in a string of attempts by the government to track down a group of international smugglers who have been exporting minerals to overseas markets in China, Italy, Vietnam and Europe.

Government statistics released last week show that the country loses Tsh2.2 billion ($1.36 million) every month on illegal export of minerals.
