The terrorists use modern weapon and not the old Soviet arms as Russia says against the Ukrainian forces in eastern region.
The news was stated by NATO Secretary General Jens Stoltenberg during his visit to Riga, Latvia where an informal meeting of the EU defense ministers takes place on Wednesday, Ukrainian TV Channel 5 reported.
"They used modern weapons against the Ukrainian military in the region of DebaltsevE," said Stoltenberg.
He expressed his concern about the crisis in eastern Ukraine and stated that it had been growing worse.
"We have seen that a ceasefire was breached. We have seen that the separatists have advanced in eastern Ukraine, especially in the area of Debaltseve," he said.
