A blast in a coastal resort in southern Turkey killed two people on Monday, a day after four explosions wounded more than 27 people, Turkish officials said, according to the BBC.
The explosion, which also wounded several people, took place near a market in the popular Mediterranean city of Antalya, the Anatolian news agency quoted police officials as saying.
A spokeswoman for the governor's office in Antalya said police were investigating the cause of the blast.
"It occurred in front of a building housing Turkish restaurants," Guzide Ormeci said.
The attack came hours after four separate bombings wounded more than 21 people.
Three blasts hit the popular Mediterranean resort of Marmaris late Sunday, including one that blew apart a minibus around midnight as many people were out in the streets.
Local governor Temel Kocaklar said 21 people, including 10 Britons and 11 Turks, were wounded in the minibus blast.
"We will catch the perpetrators of these explosions in the shortest time possible and bring them before the public," he told the Anatolia news agency.
Medics at the Ahu Hetman hospital in Marmaris told the BBC that none of the wounded Britons suffered life-threatening injuries.
Reports say the other two bombs in Marmaris exploded in rubbish bins, but nobody is said to have been injured in these explosions.
Security was immediately beefed up in the town, with extra troops called in to check cars entering and leaving the area, Anatolia reported.
The fourth bomb exploded late Sunday in Istanbul, wounding at least six Turkish citizens, local media reported.
None of the injured was in a critical condition, officials said.
Nobody claimed responsibility for the attacks.
