sentence1: At first, after the earliest attacks, the government seemed to blame the Mojahedin-e-Khalq (MeK) organization. It later expanded its accusations to allege U.S. facilitation and imply infiltration via U.S. occupied Iraq or Afghanistan, both of which share extensive borders with Iran. The MeK, which formerly operated under Saddam Hussein's protection in Iraq, has claimed bombings in the past, but vehemently denies participating in the recent spate of attacks. The group seems to have moved away from violent acts in recent years as it tries to curry favor with Western governments and shed its terrorist image (the group is currently listed on U.S. and many European terrorist watch lists). The affiliated National Council of Resistance of Iran (NCRI) has also denied involvement.
sentence2: Saddam Hussein is connected to Mojahedin-e-Khalq.
