Cuba's leader on Tuesday said the US would face "unbreakable resistance" if it tries to take over the impoverished island nation, as communist authorities scrambled to fix a nationwide electricity blackout. Cuba's government is under increasingly crushing pressure, with Washington enforcing an oil blockade and openly stating it wants to end the nearly seven-decade-old US standoff with the one-party communist state.
