Many people have been injured in an explosion in Izmir, Turkey's third largest city, police said.
"There are many injured, we are trying to figure out exactly how many," a local police officer told Reuters news agency.

The blast happened at a cafe in the Alsancak district of the Aegean city, and ambulances have taken the injured to hospitals, initial reports said.
"Two grenades were thrown into the cafe and exploded but the attack has no political links," Izmir police chief Huseyin Capkin told reporters.
The cause of the explosion was not immediately clear.
Fifteen injured people were taken to three hospitals in the area, Reuters news agency reported.
A spate of deadly bomb attacks claimed by Kurdish separatists has hit Turkey this year.
This latest attack comes a day after the separatist Kurdistan Workers Party (PKK), which in the past has carried out bomb attacks, declared a unilateral ceasefire.
Turkey's top general has rejected the ceasefire by armed rebels, vowing to fight on "until not a single armed terrorist is left".
General Yasar Buyukanit, the new chief of military staff, said the PKK must "lay down arms unconditionally and give themselves up".
The PKK's conflict with Turkey has claimed more than 30,000 lives since it began in 1984.
