Finland attack: 2 killed in Turku stabbing spree
Turku sits on the coast around 140 kilometers (around 85 miles) west of the capital, Helsinki. With a population of about 185,000, it's an important business and cultural center.
A body covered in a white sheet was photographed at the attack site.
"It was really horrible. We were sitting on a terrace just next to the square and this woman just screamed like hell and this guy was standing in front of her with a huge knife just stabbing people," he said.
"There was blood everywhere," he said, adding that he saw a victim lying on the ground.
An emegency team cordons off the attack site on Friday. Finnish media published photographs of the attack site, and one showed a body covered with a white sheet. Others showed a small crowd around someone apparently bleeding on a cobblestone road and several ambulances around a cordoned-off area. Three people are now undergoing surgery, YLE reported, citing hospital sources. Police warned the public to stay away from the city center.
