Former Cuban president Fidel Castro called President Barack Obama's speech to the United Nations last week "gibberish" in a new opinion piece.

Castro, writing his "reflections" on a Cuban government website, slammed Obama's address in his first column since July, Reuters reported on Monday. Castro said Obama - who he dubbed the "yankee president" - misrepresented the U.N. on many issues, including the situations in Iraq and Afghanistan, U.S. policy concerning Israel and Palestine and the uprisings in Arab nationals this year.

"Who understands this gibberish of the President of the United States in front of the General Assembly?" Castro wrote.
