The UK parliament's Foreign Affairs Committee has criticised the government for underestimating Russia's Wagner mercenary group.
The group has now conducted military activity in at least seven countries, the report said: Ukraine, Syria, the Central African Republic, Sudan, Libya, Mozambique and Mali.
In the scathing report, cross-party lawmakers accused the government of failing to address the risk and called for the group to be designated a "terrorist organisation".
The BBC's Frank Gardner spoke to Corin Dann.
