European timber companies have helped fund the war in the Central African Republic through lucrative deals with militia groups, campaign group Global Witness alleges in a new report.  The companies paid millions of dollars to rebel groups accused of war crimes, the report says.  It accuses the EU of failing to stop imports of illegal timber to Europe... Timber companies from France, Lebanon and China paid more than $4m (£2.5m) to rebels in 2013, mainly for protection services, the report says... Europe accounts for nearly two-thirds of timber exports from the CAR, and companies in France, Germany and Belgium have all been trading in the commodity, it says.
