"The renewed armed conflict between the two Eastern Partnership countries poses a serious threat to security in the region," Linkevicius said in a press release.

"Neither side needs confrontation. What is the most important now is to bring the situation under control decisively, make a strategic pause, cease fire and refrain from any move that could lead to a further escalation," he said.

The Lithuanian minister called on the countries to make full use of available channels of bilateral communication and underlined the need for a stronger involvement by the OSCE Minsk Group, according to the ministry.

Linkevicius also discussed the situation on the Armenian-Azerbaijani border during his phone conversation with Turkey's foreign minister.
