A bomb which went off on a bus in a Turkish holiday resort has injured 21 people - 11 Turks and 10 Britons - and another blast hurt six in Istanbul.
The blasts took place in a busy tourist area
The blast on a busy street in Marmaris was one of three to rock the resort on Sunday night but the other devices, placed in bins, caused no injury.
Some of the injured are in intensive care but none are thought to be in a life-threatening condition.
There was no immediate claim of responsibility for the attacks.
Kurdish separatists, Islamic militants and leftist extremists have all carried out attacks in Turkey in the past.
Police in Marmaris said only one device had apparently detonated properly, on the minibus in the centre of the town.
It went off under a seat on the bus and 16 of those injured were on the vehicle at the time, Turkish sources say.
A UK Foreign Office spokeswoman said she believed the 10 Britons injured were holidaymakers but that British nationals could be living in the area.
It is currently peak season in Marmaris, which is a popular holiday destination among Britons and other Europeans and has a large number of bars, restaurants and nightclubs.
Earlier on Sunday, an explosion in one Istanbul's poorer districts, Bagcilar, injured six people, police said.
The explosion occurred near the local governor's office and police said they suspected that Kurdish militants were involved.
