The agency reports, quoting unnamed NATO officials, come after U.S. President George W. Bush called on alliance members to lift restrictions to enable commanders to combat a growing Taliban threat.
Some countries had been criticized for keeping their troops out of harm's way in safer areas of Afghanistan.
Reuters quotes NATO officials as saying France, Germany, Italy, and Spain promised to send soldiers anywhere in Afghanistan in emergencies.
But Germany's Chancellor, Angela Merkel, said any help from her country in the volatile south would be temporary.
The summit ends today, following a morning working session in which leaders are expected to focus on NATO's transformation to better deal with modern security threats.
