Two Belgian teenagers found with 5,000 ants in Kenya have been fined $7,700 or the option to serve 12 months in prison for violating wildlife conservation laws.

A Kenyan court has sentenced four men to one year in prison or pay a fine of $7,700 (£5,800) for trying to smuggle thousands of live queen ants out of the country. The four suspects – two Belgians, a Vietnamese and a Kenyan – were arrested last month with live ants suspected to have been destined for collectors in Europe and Asia.

A Kenyan court on Wednesday fined four men $7,700 each for trying to traffic thousands of ants valuable to the country's ecosystem, in cases experts say signal a shift in biopiracy from trophies like elephant ivory to lesser-known species.
