The Pentagon has sharply raised its estimate of the number of US troops currently in Afghanistan. <br/><br/>The move comes ahead of a decision on adding thousands more troops under President Donald Trump's new strategy for the war-ridden country. <br/><br/>Pentagon Joint Staff Director Lieutenant General Kenneth McKenzie said, a comprehensive review showed there were approximately 11,000 uniformed US servicemen and women in Afghanistan, compared to the previous count of 8,400 troops used since last year. <br/><br/>It includes temporary and covert units as well as regular forces. The new count was made to establish the basis for an increase in troops possibly by around 4,000 under Trump's revised strategy to better support Afghan troops in the fight against the Taliban.
