Police say they have arrested four more suspects in the assassination of Haitian President Jovenel Moise, bringing the total to six detained and seven killed.

National police director Leon Charles told Radio Metropole on Thursday that police are still looking for more of those responsible for the early Wednesday’s raid in which the president was shot to death and his wife, Martine, critically wounded.

Officials have not given any details about the suspects, including their nationalities, nor did they suggest a motive for the attack, which they said was carried out by “a highly trained and heavily armed group”.

The members of the group spoke Spanish or English, it is claimed.
