The interior minister also showed a number of slides and photos illustrating where he said police snipers were firing from. He named two buildings on Khreshchatyk and Kostyolna streets, saying other spots were still being investigated.
I would like to know why is there not a definite article such as the in front of Khreshchatyk and Kostyolna streets? Or, do you think, it's totally alright as far as grammar goes? If so, could you please explain the rules governing this particular usage?

The outlet also reported that “on the Lenin avenue, two people were seriously wounded – one in the head and another in the stomach. A huge pool of blood is next to the “Arbat” café. It’s not known whether the wounded people have survived. Witnesses say they were driven away in a passenger car. The fighting is on next to the main police department, gunfire is heard. Two armored vehicles blocked the Artyom street.”
