Honduras' ousted President Manuel Zelaya waves upon his arrival at Comalapa international airport, in San Salvador July 2, 2009. A caretaker government in Honduras said on Thursday it was open to holding early elections to resolve the impasse over ousted President Zelaya, as the Organization of American States readied a mission to Honduras to push for his reinstatement. Interim government head Roberto Micheletti said holding a referendum on bringing back the leftist president to serve out the last few months of his term was also possible, although it would be "difficult" to do so immediately.
