Poland is currently under treat posed by terrorists who might carry out attacks against the country believed to be a close ally of the United States, said a report released Friday in Lodz, some 120 kilometers southwest of Warsaw.

The report was prepared by researchers from the Center of Strategic Studies and Forecasts at the School of International Studies in Lodz, the second most populous town in Poland.

Radical Islamists pose the biggest threat while "organizations like ETA or IRA are not so dangerous," said the report.

Ryszard Machnikowski, the head of the center, said it also seems unlikely that groups of Polish radical right and left could undertake terrorist actions.

In his opinion, Poland became a potential target of attacks forterrorist groups after it supported US policy and because of recent news about clandestine CIA prisons allegedly hosted by the country.

The most probable form of an terrorist attack would be an action by a suicide bomber or explosion of a car bomb, he said.

The Lodz scientists warned that Poland has yet to establish anycounterterror mechanism to cope with the pressing situation.

"It should be created although it is obvious that no system is hundred-percent effective", Machnikowski said.
