"Instead of interfering in Iraq’s affairs and implementing US plots, Saudi Arabia had better deal with his country’s internal affairs," member of the parliament’s National Security and Foreign Policy Commission Mohammad Saleh Jokar said on Sunday.
He underlined that by looking at the instability and insecurity in Iraq, one realizes the Saudi Arabia is playing a main role in these instabilities.
Last week, the Baghdad government charged that Saudi Arabia should be held responsible for financing the militants and supporting the crimes committed by insurgent groups in Iraq.
Comments from Riyadh indicate it is "siding with terrorism", the cabinet said in a statement issued by Prime Minister Nuri al-Maliki’s office.
"We strongly condemn this stance," the statement read.
"We hold it (Saudi Arabia) responsible for what these groups are receiving in terms of financial and moral support".
It continued, "The Saudi government should be held responsible for the dangerous crimes committed by these terrorist groups".
In March, Maliki accused both Saudi Arabia and Qatar of supporting terrorism in Iraq.
