NOVOAZOVSK, Ukraine - A Ukraine security spokesman says two columns of tanks from Russia have entered a strategic town.
Ukrainian security council spokesman Col. Andriy Lysenko says Ukrainian forces were fired at using Grad missile systems from Russian territory at about 11 a.m.
Lysenko says about an hour and a half later, two columns, including tanks and other fighting vehicles began an attack.
They later entered Ukraine from Veselo-Voznesenka and Maximovo of the Rostov region in Russia.
Ukrainian border guards retreated because they didn't have heavy equipment.
