Istanbul blast: One suspect detained

A person suspected of involvement in the blast that hit Istanbul's historic Sultanahmet Square on Tuesday, killing 10 people has been detained, Turkish Interior Minister Efkan Ala said on Wednesday.

The minister's remarks came at a press conference with his German counterpart, Xinhua news agency reported. Nine of the 10 killed were reportedly German tourists.

The minister said 17 others were injured, adding nine of them are German citizens, one from Peru, the rest from Norway. A total of 11 are undergoing treatment and two of them are critical, Ala said.

The Turkish minister assured foreigners visiting the country that the government has taken necessary measures to ensure security.

Turkish Prime Minister Ahmet Davutoglu on Tuesday said the attacker is a member of Islamic State (IS) group, which is blamed for a number of deadly attacks in Turkey.

Turkey has faced a series of deadly attacks.

In July 2015, a bombing attack in the border town of Suruc killed 34 pro-Kurdish and Left-wing activists.

In October, twin suicide bombings hit the capital city Ankara, claiming a total of 103 lives. Both were blamed on the Islamic State (IS) terrorist group.
