Iranian President Masoud Pezeshkian has again denied any Iranian involvement in the drone strikes targeting Azerbaijan’s Nakhchivan exclave last week.

Pezeshkian spoke by phone with Azerbaijani President Ilham Aliyev on March 8, according to the Azerbaijani Presidential Office.

Aliyev’s office said in a readout that the Iranian president stated the strike in Nakhchivan “has nothing to do with Iran” and said the incident should be investigated.

Aliyev also called for an investigation.

The March 5 drone strikes hit near Nakhchivan Airport and a local school, wounding four people. Azerbaijani President Ilham Aliyev accused Iran of carrying out the strike, but Tehran denied involvement and suggested it could have been a false-flag operation involving Israel.
