He made the remarks while commenting on Turkey's military attacks on northern Iraq.



Turkey has recently launched a series of military air and ground attacks on northern Iraq to fight rebels of the Kurdistan Workers Party (PKK) who used some bases in mountains of northern Iraq as a spring-board for attacks across the border.



Turkish aircraft attacked rebel hide-outs and ground troops clashed with Kurdish guerrillas in the area.



However, the military operations were halted on March 1 as Ankara announced that it has achieved its goals.



"Terrorism hurts everyone and all regional states are responsible to fight it," said President Ahmadinejad speaking after a meeting with Head of Islamic Supreme Council of Iraq, Abd al-Aziz al-Hakim.



The Iranian president arrived in the Iraqi capital on Sunday for landmark visit by an Iranian president since the 1979 Islamic Revolution in Iran.



A ranking delegation is accompanying the president including Foreign Minister Manouchehr Mottaki as well as ministers of energy, economy and transport and a group of Majlis deputies.



The president said his visit aimed at consolidating bilateral friendly relations as well as cementing bilateral ties and cooperation between the two neighboring states.
