PORT-AU-PRINCE (Reuters) - Haiti’s national police has lost nearly 3,300 officers in three years, according to data from the force’s main trade union, as under-gunned security officials battle powerful gangs estimated to control most of the capital.

Nearly nine in 10 of those were sacked for abandoning their posts, according to a report which SYNAPOHA trade union’s general coordinator Lionel Lazarre shared with Reuters on Monday, while 123 more resigned.

Lazarre estimated some 80 police officers were killed in action, died in accidents or disappeared last year.
