Turkish Chief of General Staff Yasar Buyukanit called on all countries to cooperate to fight against terrorism, the semi-official Anatolia news agency reported on Tuesday.
Terrorism has no religion, nationality, regional ties or ideology, and a terrorist attack staged in one country can affect others, Buyukanit said in his article published in the latest issue of Defense and Aviation magazine.
"Although international war against terrorism is being discussed in every platform and many important organizations such as the United Nations, the North Atlantic Treaty Organization and the European Union have made remarks and decisions regarding harsh measure (against terrorism), necessary measures have not been taken yet," he said.
"This stance has not only encouraged terrorists but also widened dimensions of the (terrorist) acts," he commented.
According to Buyukanit, one of the leading problems faced in international fight against terrorism is the lack of a consensus on the definition of terrorism.
"However, this should not be an obstacle in combating terrorism, " he said.
In order to conduct an effective fight against terrorism, countries should first investigate financial sources of terrorist organizations and their relationship with international organized crime gangs, the Turkish army's chief said.
He also emphasized that terrorist organizations have been involved in illicit drug, human and arms trafficking, noting that these illegal activities must be stopped in order to counter terrorism.
Last month, Buyukanit said that a military operation must be launched to crack down on the camps of the outlawed Kurdish Workers' Party (PKK) in northern Iraq.
The PKK, which was listed as a terrorist organization by the United States and the European Union, launched an armed campaign for an ethnic homeland in the mainly Kurdish southeastern Turkey in 1984, sparking decades of strife that has claimed more than 30, 000 lives.
The intensity of the fighting eased after PKK leader Abdullah Ocalan was captured and imprisoned in 1999, but fighting has flared up again in recent years.
