Australia announces 'second phase' of Russia sanctions over Ukraine assault

Australia hit Russia with a "second phase" of sanctions on Thursday over its assault on Ukraine, the first salvo in an expected battery of new international measures to punish Moscow.

Prime Minister Scott Morrison condemned Russia's "illegal invasion" as he announced sanctions against 25 individuals, four entities involved in developing and selling military gear, and restrictions on four financial institutions.

"Vladimir Putin has fabricated a feeble pretext on which to invade. Russia's disinformation and propaganda has convinced no one," Morrison said.

He flagged further waves of sanctions would be imposed "as we identify those responsible for these egregious acts", including against 300 members of the Russian parliament.
