The daughter and son-in-law of Missouri politician Ben Baker have been killed in Haiti while working there as missionaries.

Baker, a Republican, said in a post to his social media that his 21-year-old daughter Natalie and her 24-year-old husband Davy were attacked by gangs on Thursday evening.

In an emotional statement, Baker said: ‘My heart is broken in a thousand pieces. I’ve never felt this kind of pain.”

Baker says his daughter and son-in-law were full time missionaries in Haiti.

Haiti descended into a new wave of chaos after attacks in February where gunmen seized control of police stations and attacked the airport in the capital Port-au-Prince.
