There is "no military solution solely" to the Libyan conflict, the NATO chief said on Sunday.

"In conclusion we have stopped Gaddafi in his track, his time is running out, he's more and more isolated," asserted NATO Secretary-General Anders Fogh Rasmussen in an interview with CNN's "State of the Union" program.

When asked what NATO is going to do to break the stalemate on the ground between the Libyan opposition forces and government military, Rasmussen replied: "First of all, we have to realize there's no military solution solely. We will need a political solution."

Rasmussen reiterated that the NATO-led mission in Libya is accomplished only when its three very clear military objectives are fulfilled, which are "a complete end" to all attacks against civilians, a "free and unhindered and immediate access" for humanitarian assistance and a withdrawal of government troops to their bases and barracks.
