The Armenian Embassy has lodged a formal protest with other diplomatic missions in Brussels after its ambassador claimed to have been on the receiving end of death threats from his Azerbaijani counterpart, reports Politico.

A letter circulated to envoys last week alleged that Armenian Ambassador Tigran Balayan was “verbally attacked and intimidated” by Azerbaijani Ambassador Vaqif Sadiqov, who “voiced explicit threats against his life."

The incident is said to have happened at a reception in Brussels, hosted by the Turkish Embassy in honor of the country’s national day. It is understood to have been the first Ankara-sponsored engagement the Armenian Embassy had been invited to after the 2020 war.

However, Sadiqov denied the incident had taken place, saying such allegations were “becoming ridiculous.” According to him, the reception had “good food, nice people” and was a “standard diplomatic event as usual.”

“I am not aware of any letter or allegation—Armenian diplomats can claim whatever they want,” he added.
