(Reuters) - Just days before Rio de Janeiro hosts the Olympics, the city's Mayor Eduardo Paes has taken to Twitter to slam critics of his role in preparing for the Games.

Paes tends not to pull punches with critics, sometimes literally. In 2013, he hit a constituent in the face after the man lambasted the mayor as he dined with his wife.
