A siren will sound in Ansan, Gyeonggi Province, on Friday in remembrance of the victims of the Sewol ferry tragedy seven years ago.
Danwon district authorities said a one-minute siren will blare across the area starting at 4:16 p.m., in reference to the day South Korea was rocked by one of its worst maritime disasters on April 16, 2014.
More than 300 people died when the Sewol sank in waters off the country's southwestern coast, most of them Danwon High School students on a field trip.
A memorial is also scheduled be held earlier the same day at Ansan's Hwarang Park.
Other smaller ceremonies will be held nationwide.
