ISTANBUL, Turkey — A group of men stopped a passenger bus and tossed gasoline bombs at it, causing the vehicle to careen into pedestrians, killing three, in Turkey's largest city Sunday as pro-Kurdish riots continued to spread.
In the country's heavily Kurdish southeast, a pro-Kurdish demonstrator was killed, and local officials blamed police for his death.
Clashes between Kurdish demonstrators and security forces have spread from the southeast to Istanbul, which has a large Kurdish population.
In the attack in Istanbul's Bagcilar district, the bus driver backed up his flaming vehicle onto a sidewalk after the bombing, running down a group of people nearby, police said. Television images showed the bus propped up on the sidewalk and flames shooting out of every broken window. Police said two of the killed were elderly women.
Private NTV television said men had gathered around after the attack and shouted slogans for an outlawed Kurdish separatist group that is considered a terrorist organization by the United States and the European Union.
If the bus attack is found to have been carried out by pro-Kurdish demonstrators, it would bring to 12 the number of people killed in related violence in the last week.
