Russian President Vladimir Putin has canceled plans for his forces to storm the Azovstal plant in the besieged city of Mariupol, saying he instead wants them to continue blockading it. Putin told his defense minister, Sergei Shoigu, it was "inadvisable" to storm the sprawling industrial plant, where more than 2,000 Ukrainian servicemen are said to remain. "We must always think...about preserving the life and health of our soldiers and officers," Putin said, according to a transcript on the Kremlin's website.
