Russian threats and warnings to G7 and grain deal.

Russia threatens to shut down the Black Sea Grain deal with Ukraine if the G-7 nations decide to ban all exports to Russia. The G-7 countries are considering a near-total ban on exports to Russia, which would add to the list of goods that would no longer be sold to Russia. Meanwhile, Russian mercenaries have been instructed not to capture prisoners of war, but to "kill everyone on the battlefield." The Russian Ministry of Defense is trying to replenish soldier ranks depleted by the war without creating unrest caused by last fall's partial mobilization. Ukraine is poised to begin a counteroffensive to liberate more territories Russia has occupied in the months since the invasion began.
