Initial Russian response is cautious. Serbia should accept as much of the ultimatum as possible and not resist if invaded and appeal for international support.

Later the Serbs hear that the Russian Council of Ministers is prepared to take strong action including mobilisation.

6.00 P.M. The Serbs give their reply to the Austrian minister. He says it is unsatisfactory. He breaks off diplomatic relations and returns to Vienna.
