HAVANA - Cuba's Fidel Castro on Thursday criticized the way in which Osama Bin Laden die, saying that despite his crimes it was not warranted to kill him in a situation where he was un-armed with his family.

Castro, in his regular column "reflections" published in the official Cuban daily Granma, said that the United States had committed "an abhorrent deed" when they decided to pursue "the killing of a human being disarmed and surrounded by his family" while he also criticised the sea burial of the leader of the terrorist group al-Qaida.

"To murder him and send him to the depth of the sea shows fear and insecurity and makes him a much more dangerous character," said the former Cuban leader.

Castro, said that terrorism never can be solved through acts of violence and war, and US citizens celebrating the death of Bin Laden through grand public displays only worsened their own security situation in front of radical Islamic groups as they were acting no better than those radical groups calling for the death of America in the Middle East.

"After the initial euphoria, far from protecting the US citizens, the feelings of hatred and revenge against them will multiply," he said.

Expressing regret of the way the US was handling the death of Bin Laden, Castro recalled how Cuba on September 11, 2001 had offered help and cooperation to the US immediately after the attack on the Twin Towers of the World Trade Center.

"Cuban people expressed its solidarity with the United States and offered its modest cooperation in the field of health to the victims of the brutal attack on the Twin Towers in New York," he said, adding that Cuba also had offered the US to use its airstrips.

But following the attacks, the United States launched what Castro said is "unfair wars" in Iraq and Afghanistan and applied "intolerable and maddening torture" on prisoners at the Guantanamo Naval Base.

Fidel Castro started handing over power to his younger brother Raul in 2006 after falling ill and undergoing surgery for a serious intestinal condition, but he keeps writing editorials on the issues of world interest.
