The authorities in Azerbaijan have arrested 22 people on suspicion of spying for Iran, accusing them of links to the Iranian Revolutionary Guards.
The undated arrests were confirmed in a brief statement by the Azerbaijani national security ministry.
Azerbaijani TV reported last month that a plot to attack the Israeli embassy and a Jewish centre had been foiled.
At the time, Iran was also suspected of attacking Israeli targets in Thailand, India and Georgia.
It was not immediately clear on Wednesday if these were new arrests, or official confirmation of those made in February.
The 22 detainees are said to have received orders from the Revolutionary Guards to “commit terrorist acts against the US, Israeli and other Western states’ embassies and the embassies’ employees”.
