Turkish security forces have arrested four people in connection with the suicide bombing in Istanbul in which 10 German tourists were killed, Turkish prime minister Ahmet Davutoglu has said.
Tuesday's blast in Sultanahmet Square killed 10 German tourists and wounded 15.
The majority of the 10 people killed in the explosion in central Istanbul earlier today were German citizens, Turkey's Prime Minister Ahmet Davutoglu has told Angela Merkel by phone, according to Reuters.
Mr Davutoglu told the German Chancellor that an investigation into the apparent suicide attack, which also wounded at least 15 people, would be shared with German officials.
Earlier, Ms Merkel had expressed worry that some fellow Germans may have been caught up in the tragedy, saying the world must act against terrorism.
"International terrorism has shown its ugly face," said Merkel. "We need to act decisively against it."
