Sybiha announced the phone call in a post on X, according to Ukrinform.

"Diplomacy is about direct conversation, even when it’s difficult. I stressed that our goal is to avoid unnecessary escalation," Sybiha said.

He reiterated that all of Ukraine's actions are aimed solely at defending the country against Russian aggression and have never been intended to target civilian vessels or civilians.

Sybiha noted that this also applies to Iran's claims regarding the death of one of its citizens and damage to a civilian vessel in one of the recent incidents.

"Our goal is to counter Russian aggression, which is the root cause of all incidents, and it is Russia who bears full responsibility for all provocations and casualties," Ukraine's top diplomat stressed.

Sybiha also emphasized the necessity to refrain from any escalatory steps, as well as to end any support for Russia’s war against Ukraine.

"This war is illegal and it must end. Our position remains unchanged: Europe and the Middle East deserve stability, security, and peace," he said.
