Wuppertal, Germany  - Three Kurdish men were remanded in custody in Germany Monday on attempted murder charges, accused of throwing a petrol bomb at Turkish club-rooms the previous day.

Police in the western city of Wuppertal said they were checking if the trio, aged 19, 23 and 27, were behind similar arson attacks on ethnic Turkish clubs and offices in the nearby cities of Dusseldorf and Dortmund.

The men live in the city of Bochum, but were being held in Wuppertal, prosecutors said. Investigators will also study whether the men are linked to the PKK, the radical Kurdish group opposed to Turkish control of ethnic Kurdish areas.

Petrol bombs usually consist of glass bottles of petrol with a lighted wick to make the fuel burn. (dpa)
