In the southwestern city of Stuttgart, one person was slightly injured in an arson attack against an Islamic cultural center used by Turks as a mosque. The assailants broke a window and then set the blaze while several people were inside, police said.

In the northern city of Bremen, three Turkish travel agencies were petrol-bombed in a 15-minute spate of attacks shortly after midnight. Several people who lived over the agencies had to be saved. Two other Turkish travel agencies and two cultural associations were targeted in Wuppertal, a fast-food restaurant in Bielefeld and a Turkish store in Moenchenglad Bach, all western cities.

In Berlin, three masked men entered a Turkish cafe and threw petrol bombs but firefighters brought the blaze quickly under control. German InteriorMinister Otto Schily had Tuesday appealed for calm after Ocalan's sentencing and said he hoped the sentence would be reduced. Schily called on ``all Kurds to stay calm and not take rash actions but instead Have confidence in an appeal or later a hearing before the European court of human rights''.

In February, Ocalan's arrest in Kenya sparked led to the fatal shooting of four Kurdish demonstrators by guards at the Israeli embassy here. About 2,000 Kurds also demonstrated across Germany on May 31 when Ocalan's trial opened. Germany is home to one of the largest Kurdish minorities in Europe. There are around half a million ethnic Kurds in a population of around two million Turkish nationals.
