Amsterdam - The Netherlands on Monday recalled its ambassador to Iran after staff members at its embassy in Tehran were expelled, Foreign Minister Stef Blok said.

"Have decided to recall the ambassador in Tehran for consultations," Blok said in a tweet. "The decision follows the expulsion of two Dutch embassy staff. That is unacceptable."

The Netherlands has recalled its ambassador from Tehran in a dispute over an alleged Iranian plot to assassinate regime opponents on Dutch soil, the Dutch foreign minister said Monday.

Iran expelled two Dutch diplomats in February in a row over the murders of two Iranian dissidents in 2015 and 2017.
