Children play in pools set up at Gwanghwamun Square in Seoul on June 4, a day when the Sejong thoroughfare road was pedestrian only. Throughout the hot summer months, the area will be closed to cars on the first and third Sundays of every month until October. The square was the site of candlelight protests that pushed for the impeachment of former President Park Geun-hye. (by Kim Seong-gwang, staff photographer)
