Taliban forces held a military parade in Kabul on Sunday using captured American-made armoured vehicles and Russian helicopters in a display that showed their ongoing transformation from an insurgent force to a regular standing army. The parade was linked to the graduation of 250 freshly trained soldiers, defence ministry spokesman Enayatullah Khwarazmi said, according to news agency Reuters. The exercise involved dozens of U.S.-made M117 armoured security vehicles driving slowly up and down a major Kabul road with MI-17 helicopters patrolling overhead. Many soldiers carried American made-M4 assault rifles. Watch this report for more.
