South Korea raised the travel advisory level for Istanbul on Wednesday, a day after a deadly terrorist attack killed 10 people and injured 15 others, including a South Korean college student.

A Syrian suicide bomber targeted a popular tourist destination in the Turkish city on Tuesday, with the Islamic State jihadists blamed for the attack.

South Korea had previously placed the former Turkish capital on the lowest travel advisory level of "blue" out of the four existing ones.

The level has now been raised to the second-lowest level of "yellow," which advises citizens to take "special precautions" and reconsider traveling there.

Only the southwestern part of Turkey including its borders to Syria and Iraq had been put under "yellow" or "red" advisory prior to Tuesday's incident.

In a statement earlier Wednesday, the South Korean government condemned the attack and expressed condolences to the victims.

"Our government supports the Turkish government's efforts to eradicate terror and will continue to join the international community's relevant efforts," the Foreign Ministry said. (Yonhap)
