Eight police officers and three soldiers were wounded by a bomb which tore through a minibus in the western Turkish city of Izmir, Turkey's third largest city. According to sources the explosion was believed to be caused by remotely detonated plastic explosives.
Islamist militants and Kurdish guerrillas have carried out frequent attacks in Turkey in the past. Officials have blamed the bombings on Kurdistan Workers Party (PKK) guerrillas, which took up arms against the Turkish state in 1984 with the aim of creating an ethnic homeland in southeast Turkey. Around 40,000 people have been killed in the conflict.
On August 19 a suicide bomber detonated explosives in his vehicle in the southern province of Mersin, killing him and injuring nine police officers. Sources say the explosives used in the Mersin blast were the same type used in a double bombing in Istanbul in July, which killed 17 people.
Last month's attacks in Turkey were the worst since 2003, when Islamist militants killed over 60 people in a series of bombings in Istanbul.
