At least seven members of the terrorist Mujahedin-e Khalq Organization (MKO) have been killed and more than 50 others injured after mortars landed in Camp Liberty near Baghdad, the capital of Iraq.
The attack took place early Saturday, when a number of Iraqi policemen were also injured.
No group has yet claimed responsibility for the attack.
Members of the MKO terrorist group are being transferred from Camp New Iraq, formerly known as Camp Ashraf, which is situated about 120 kilometers (74 miles) west of the border with Iran, to the Camp Liberty near Baghdad Airport.
The United Nations High Commissioner for Refugees said that Camp Liberty should be used as a transit center for the MKO members to other countries.
Head of the Security Committee of Iraq’s Diyala Province Meysam al-Tamimisaid said earlier in February that the MKO had turned its Camp Ashraf into a base for training al-Qaeda operatives who carry out terrorist attacks against the Iraqi nation.
He added that a large amount of money and weapons was also funneled through Camp Ashraf to al-Qaeda and Salafist extremist groups to help them target Iraqis in acts of terror.
The MKO fled to Iraq in 1986, where it enjoyed the support of Iraq's executed dictator Saddam, and set up its camp near the Iranian border.
The US-backed group is also known to have cooperated with Saddam in suppressing the 1991 uprisings in southern Iraq and carrying out the massacre of Iraqi Kurds.
The MKO has carried out numerous acts of violence against Iranian civilians and government officials.
