Washington: US President Barack Obama has confirmed that NATO will take command of the military operation in Libya on Wednesday.

In his address to the nation on his policy on Libya, Obama on Monday said the most effective alliance, NATO, has taken command of the enforcement of the arms embargo and no-fly zone.

“On Monday night NATO decided to take on the additional responsibility of protecting Libyan civilians. This transfer from the United States to NATO will take place on Wednesday,” he said, adding that going forward, the lead in enforcing the no-fly zone and protecting civilians on the ground will transition to US allies and partners.

Because of the transition to a broader NATO-based coalition, the risk and cost of this operation to our military and to American taxpayers will be reduced significantly, Obama noted.

"So for those who doubted our capacity to carry out this operation, I want to be clear: the United States of America has done what we said we would do," he said.

Secretary of State Hillary Clinton is travelling to London where she will meet with the Libyan opposition and consult with more than thirty nations, he said, adding that these discussions will focus on what kind of political effort is necessary to pressure Gaddafi, while also supporting a transition to the future that the Libyan people deserve.
