Breaking News-RTRS-UPDATE 5-Ecuador defaults, says to fight "monster" creditors

GUAYAQUIL, Ecuador, Dec 12 (Reuters) - President Rafael Correa declared a default on Ecuador's foreign sovereign bonds on Friday, vowing to fight "monster" debt-holders in court in one of most aggressive moves against investors in the region for years.
Correa, a U.S.-trained economist and ally of Venezuela's anti-U.S. President Hugo Chavez, refused to make a $31 million interest payment due on Monday on 2012 global bonds, saying the debt was contracted illegally by a previous administration.
