Russian tanks, armored vehicles enter southeast Ukraine

A column of Russian tanks and armored vehicles has crossed into southeastern Ukraine, away from where most of the intense fighting has been taking place, a top Ukrainian official said Monday. Col. Andriy Lysenko, a spokesman for Ukraine’s National Security Council, told reporters that the column of 10 tanks, two armored vehicles and two trucks crossed the border near Shcherbak and that the nearby city of Novoazovsk was shelled during the night from Russia.
