Iranian Foreign Ministry Spokesman Ramin Mehmanparast has denounced the US support for acts of te rror, urging Washington to fulfill its anti-terror commitments.
"All countries and governments have legal commitments to counter and fight against terrorism. We call on US officials to remain committed to these commitments as support for terrorist groups runs counter to international regulations," IRNA quoted Mehmanparast as speaking at his weekly press conference on Tuesday.
In response to a question about the US and Britain's support for the Mujahedin-e Khalq Organization (MKO) terrorist group, the Iranian spokesperson said that the cell has a compelling record of terrorist activities.
Mehmanparast added that the public opinion throughout the world strongly condemns the support of Western countries for such terror groups by giving them safe haven.
He went on to say that the MKO has inflicted heavy damage on the Iraqi people, stressing that the Iraqi nation and government are firmly resolved to expel the terrorists from their country.
The MKO is especially notorious in Iran for having sided with executed Iraqi dictator Saddam Hussein during the 1980-1988 Iraqi-imposed war on Iran.
It has also claimed responsibility for numerous terrorist attacks and the assassination of significant figures and ordinary civilians in Iran over the past three decades.
The group is listed as a terrorist group by Tehran and much of the international community.
