NATO is delaying its takeover of all military operations in Libya by 24 hours to March 31 at 0600 GMT (2pm Singapore time), an alliance diplomat said on March 29, AFP reported.

The 28-nation military organization agreed on March 27 to take command of the U.S.-led campaign, and U.S. President Barack Obama said the transfer would be completed on March 30.

But the diplomat, who spoke on condition of anonymity, said an extra day was needed for a smooth transition from U.S. to NATO command, according to The Straits Times.

The delay is also necessary because contributions from some allies could depend on the outcome of an international conference on Libya taking place on March 29, the diplomat said.

“NATO will effectively take over command of Libyan operations on Thursday at 0600 GMT,” the diplomat said.
