YANGON (Reuters) - Myanmar leader Aung San Suu Kyi admitted on Thursday that war crimes may have been committed against Rohingya Muslims but denied genocide, saying refugees had exaggerated the extent of abuses against them.

In an opinion piece published in the Financial Times ahead of an initial International Court of Justice (ICJ) ruling on the issue, she said Myanmar was the victim of "unsubstantiated narratives" by human rights groups and U.N investigators.
