New Delhi: While the Russian army has been directed by Putin to launch an attack on Ukraine "from all directions", a Ukrainian company in charge of building and maintaining roads said it was removing all road signs that could be used by invading Russian forces to find their way around the country.
"The enemy has poor communications, they cannot navigate the terrain," the company Ukravtodor said in a Facebook update late on Friday.
"Let us help them get straight to hell", read Ukravtodor's Facebook statement.
It posted an edited photo of a standard road sign in which directions to nearby cities have been replaced with profanities that could be translated as "Go f*** yourself", "Go f*** yourself again" and "Go f*** yourself back in Russia".
Meanwhile, the Russian troops have now entered Ukraine's second-largest city - Kharkiv - after launching explosions and missiles on Kyiv, Reuters reported.
"The Russian enemy's light vehicles have broken into Kharkiv, including the city centre," said regional governor Oleh Sinegubov. "Ukraine's armed forces are destroying the enemy. We ask civilians not to go out."
Videos published by Anton Herashchenko, adviser to the interior minister, and Ukraine's State Service of Special Communications and Information Protection showed several light military vehicles moving along a street and, separately, a burning tank.
The Ukrainian president’s office said Russian forces blew up a gas pipeline in Kharkiv, the country’s second-largest city.
The State Service of Special Communication and Information Protection warned that the explosion, which it said looked like a mushroom cloud, could cause an “environmental catastrophe" and advised residents to cover their windows with damp cloth or gauze and to drink plenty of fluids
