"It is not the senate as a whole adopting the text of the petition. It was a private initiative of some senators," an information official at the senate, speaking on condition of anonymity, told IRNA.

The official noted that not all the senators had signed the petition which called on the EU to remove the MKO from its list of terrorist groups.

"We are not concerned about it," added the official.

According to local media reports, 41 out of the 71 Belgian senators had signed the petition last week.

A Belgian Foreign Ministry spokesman said the government has no intention of calling on the EU to remove the MKO's name from the terrorist list.
