One person has been killed and nine people remain missing, including a child, after a seaplane crashed in Puget Sound in Washington state, the US coast guard said.

The floatplane had been flying on Sunday afternoon from Friday Harbour, a popular tourist destination in the San Juan Islands, to Renton, a southern suburb of Seattle, the agency said.
