US Defense Secretary Jim Mattis said that a number of US allies are ready to increase their troop numbers in conflict-torn Afghanistan as part of efforts to fight against local terrorists, the US-funded Radio Sawa reported.

"I have directed the Chairman of the Joint Chiefs of Staff to make preparations to carry out the president’s strategy. I will be in consultation with the Secretary General of NATO and our allies—several of which have also committed to increasing their troop numbers. Together, we will assist the Afghan Security forces to destroy the terrorist hub," Mattis said in a statement on Monday.
