French cement maker Lafarge has been found guilty of paying millions of dollars in protection money to jihadist groups, including the group calling itself Islamic State (IS), to keep its business running in Syria during the civil war.

Eight ex-Lafarge employees were also found guilty of financing terrorism, including former CEO Bruno Lafont who was jailed for six years on Monday.

The court in Paris found that Lafarge paid groups $6.5m (€5.59m; £4.83m) between 2013 and 2014 to keep its plant operating in northern Syria.

Judge Isabelle Prevost-Desprez said such payments had allowed proscribed organisations to gain control of the country's natural resources, enabling them to finance attacks across the Middle East and Europe.

"It is clear to the court that the sole purpose of the funding of a terrorist organisation was to keep the Syrian plant running for economic reasons. Payments to terrorist entities enabled Lafarge to continue its operations," Prevost-Desprez said.
