ISTANBUL - Turkish police detained two suspects with automatic weapons after a shooting on Wednesday near the entrance to Istanbul's Dolmabahce palace, popular with tourists and home to the prime minister's Istanbul offices, the Dogan news agency said.
Ambulances were sent to the area around the building and roads were sealed off by police, but there were no reports of casualties. Dogan said the attackers had targeted police officers stationed at the entrance to the palace.
Some local media reports suggested there had also been an explosion but there was no independent confirmation of this.
Prime Minister Ahmet Davutolgu was in the capital Ankara as reports of the attack emerged and did not interrupt a speech being broadcast on live television.
