Venezuelan President Hugo Chavez pledged Thursday that Venezuela will support Iran if it is invaded as a result of the Middle Eastern nation's high-stakes nuclear standoff with the United Nations Security Council.

"Iran is under threat; there are plans to invade Iran, hopefully it won't happen, but we are with you," Chavez told Iranian President Mahmoud Ahmadinejad at a meeting of the Group of 15 developing nations.

The U.N. has demanded that Iran suspend uranium enrichment amid concerns by some nations that it could be used for nuclear weapons. Iran insists that its enrichment efforts are peaceful, aimed solely at producing electrical energy.

Chavez said Venezuela stands with Iran in this time of crisis, just as it has with Cuba, where Fidel Castro handed over power to Raul while recovering from intestinal surgery. If they don't defend each other, no one else will, Chavez said.

"Under any scenario we are with you just like we are with Cuba," Chavez said. "If the United States invades Cuba, blood will run... We will not have our arms crossed while bombs are falling in Havana or they carry Raul off in a plane."
