An unlawful killing?
The killing of Osama bin Laden is clearly a big success for US President Barack Obama - but a legal expert here in Sweden says that the operation probably broke international law.
The American authorities revealed last night that bin Laden was not armed when he was killed. Plus that the Pakistani authorities were not informed of the operation in advance.
Said Mahmoudi is a professor in International Law at Stockholm University. He says that even the worst terrorist in the world still has the right to be arrested and put on trial.
But under the circumstances, Professor Mahmoudi says that it is entirely understandable why the American government acted this way - given the difficulty of capturing and bringing bin Laden to trial, plus the status of the Al Qaida leader as America's most wanted man.
