US Defense Secretary Jim Mattis arrived unannounced in Afghanistan on Monday to assess America's longest war as the Trump administration weighs sending more troops, ABC News reported.

Kabul was the final stop on a six-nation, week-long tour Mattis said was intended to bolster relations with allies and partners and to get an update on the stalemated conflict in Afghanistan. He is the first member of President Donald Trump's Cabinet to visit Afghanistan.
