The White House has authorised sending military and weapons support to Kurdish forces fighting Islamic State in Syria.
The Chief Spokesperson for the Pentagon, Dana White, said Donald Trump had authorised the weapons shipment to the Kurdish People's Protection Units (YPG) on Monday.
In a written statement, White said the move was intended to ensure "a clear victory" over Isis in the caliphate's self-declared capital of Raqqa, as they were the only force which might be able to reclaim the city.
However, the move has thrown a spanner in the works for the US's ties with Turkey, as the decision was met with intense opposition from the NATO ally.
The Turkish government claimed YPG is linked to Kurdistan Workers' Party (PKK) militants, who have been in conflict with the Government since 1984.
