North Korean leader Kim Jong Un has sent a letter to Chinese President Xi Jinping expressing sympathy over the harrowing crash of a Chinese plane carrying 132 people, state media said on Tuesday.

In the letter sent after Monday’s crash, Kim said he hoped China could “eradicate the aftereffects of the incident as early as possible and the bereaved family members would overcome sorrow and lead a stabilized life” under Xi’s leadership, according to a report from the Korean Central News Agency (KCNA).
