Iranian Foreign Minister Mohammad Javad Zarif took a swipe at the Western governments and the UN nuclear watchdog for ignoring the Israeli regime’s silent expansion of the Dimona nuclear site, Tasnim reports.

“Israel is expanding Dimona, the region’s only nuclear bomb factory,” Zarif said in a post on his Twitter account on Saturday.

Tagging US President Joe Biden, the IAEA, British Prime Minister Boris Johnson, French President Emmanuel Macron and German Chancellor Angela Merkel, the top Iranian diplomat tweeted, “Gravely concerned? Concerned? A little? Care to comment? I thought so.”

Zarif’s tweet came after newly-released satellite images revealed that the Israeli regime — the sole possessor of nuclear arms in the Middle East — is conducting “significant” constructive activities at the Dimona nuclear facility.
