The situation in the South Caucasus region is rapidly deteriorating as Armenia and Azerbaijan continue to build up troops along the contact line in the region, Iranian news agency Mehr reports.

Iran made it clear that it is closely monitoring the developments and will not tolerate “any geopolitical changes on its doorstep,” the media outlet notes.
“Over the last few days, the authorities of Baku and Yerevan traded accusations of trying to initiate new major military escalations. Videos and photos circulating on social media indicated that the accusations may be rooted in reality as both countries have moved to reinforce their troops along the border. 
In parallel, the leaders of Baku and Yerevan started discrete diplomatic campaigns to win over regional and international heavyweights in apparent anticipation of a major escalation of tensions. 
Iran is closely following the developments as they unfold,” Mehr writes.
The agency also mentioned the meeting in Baku between an Iranian military delegation and Azerbaijan's Defense Minister, Zakir Hasanov, where they discussed security issues in the region.
“The timing of the meeting suggests that the Iranian delegation might have conveyed a message from Iran regarding the prospect of new escalations between Baku and Yerevan. 
Iran has offered help to achieve peace and security in the South Caucasus region through diplomatic means. But it also said it cannot accept any use of force in the region to dictate new geopolitical realities. It remains to be seen whether Baku and Yerevan heeded the Iranian calls,” says Mehr.
