Work has started again at the biggest diamond mine in Tanzania amid a dispute with the government who seized a parcel of diamonds at the airport.

Operations at Petra’s Williamson diamond mine have resumed after four days of stoppage.

A week ago, shares of the British company Petra fell 7% after its diamonds were blocked from export by the Tanzanian government and several of its employees were questioned by country’s authorities.

The authorities seized a parcel of diamonds which is yet to be released.

The company’s discussions with the government over the matter are ongoing, says Petra in their statement.

The biggest diamond mine in the country was accused of under-declaring the value of its diamonds. The government alleged that Petra registered the consignment to be $14.8m (£10.9m) instead of its actual worth of $29.5m.

Petra denied the allegations, saying the government is responsible for confirming declared values.

Williamson mine in North Western Tanzania is majority owned by Petra at 75% and 25% is owned by the Tanzanian government.

The mining industry is under pressure from the government over reporting and under declared profits.

The EU is wrongly allowing foreign ships from China and Europe to fish off the coast of West Africa, campaign group Oceana has told the BBC.

It comes as several countries in West Africa attempt to put an end to foreign ships shipping illegally in their waters.

"Western African coastal states are very vulnerable to illegal fishing, which accounts for an estimated 40% of all fish that's caught in the region", Beth Lowell, a senior director at Oceana, said.

"Fish makes up the majority of a population's daily animal protein intake in the Gambia, so large fishing vessels are taking away the food security that these countries need to provide protein and nutrients for their own people".

Criminal networks smuggling rhino horn out of Africa are turning it into jewellery to evade its detection in airports, an investigation has found.

Wildlife trade monitoring network Traffic revealed an "emerging trend" of making and smuggling beads, bracelets and bangles and rhino horn powder.

The lead investigator told BBC News the trade in rhino horn was now "morphing" into a market for luxury items.

The primary destinations for smuggled rhino horn remain the same; the largest markets are in China and Vietnam. But this investigation also found that smuggling routes constantly changed and adapted, becoming more complex in order to avoid countries and airports where law enforcement resources were being focused.

This shift in how horn is processed before it is moved could make it more difficult to detect.
