Following the raw between Saudi and Iranian regime over the Saturday night embassy conflict, Kuwait pulled out its ambassador to Tehran from Iran on Tuesday.
The Kuwaiti news agency, KUNA, said this action was in response to the Iranian regime attack on the Saudi embassy in Tehran. 
On Monday, Bahrain and Sudan followed suit and severed or reduced their diplomatic relation with Iran.
The UAE also decreased its diplomatic ties with Iran and pulled out its ambassador from Tehran.
