Foreign Secretary Liz Truss has announced a fresh support package for the western Balkans as tensions erupt amid the Russian invasion of Ukraine.

In a joint news conference in Sarajevo with her Bosnian counterpart, Bisera Turkovic, Ms Truss announced the support package would be aimed at mobilising 100 million US dollars (£80 million) of UK-backed investment in a bid to counter Russian influence in the region.

She said Moscow's interference in Bosnia Herzegovina threatens a return of the civil war which tore the country apart in the 1990s.

"What we are seeing today in this country are signs of Russian interference which risks plunging us back into those dark days. This must be stopped," she said.
