The president offered a prayer for the victims, and conveyed his condolences to the families and expressed his hope for the safe return of those still unaccounted for.

He also paid tribute to the hundreds of rescue workers and volunteers engaging in a life-or-death struggle to save more lives.

Lee's message was also posted in English and Chinese.
