Putin says 'Strikes on power grids payback for Crimea drone attack'

President Vladimir Putin said Russian strikes on Ukrainian infrastructure and a decision to freeze participation in a Black Sea grain export program were responses to a drone attack on its fleet in Crimea. Putin said that Ukrainian drones had used the same marine corridors that grain ships transited under the U.N.-brokered deal, to back his claims. 'That's not all we could have done,' the Russian President warned during a televised news conference.
