A helicopter carrying Mexican Interior Minister Francisco Blake crashed in the south of Mexico City on Friday, Mexican media said.

Blake, 45, was travelling between Mexico City and the state of Morelos just to the south, his ministry said.

It was not clear whether the minsiter had survived the crash or what caused it.

Mexico is locked in a brutal conflict against drug cartels that has killed 45,000 people in the last five years.
