The person who left the bomb that caused Istanbul's explosion was arrested by the police, Interior Minister Suleyman Soylu said on Monday according to state-run Anadolu agency's English-language Twitter account.

Six people were killed and 81 others wounded on Sunday when an explosion rocked a busy pedestrian street in Istiklal Avenue in central Istanbul in what Turkish President Tayyip Erdogan called a bomb attack that "smells like terrorism".
