ISTANBUL (Reuters) - Turkish police carried out a controlled explosion of a bag left in Istanbul's popular Taksim square on Saturday, a Reuters witness at the scene said, hours after the U.S. embassy warned of "credible threats" to tourist areas.
Police cordoned off Taksim, a square lined with hotels and restaurants frequented by tourists, while a member of the police bomb squad was seen opening what appeared to be a bag, the witness said. The bomb squad later detonated it in a controlled explosion, causing a loud boom to echo across the square, the witness said.
