Thousands of Pakistani troops deployed near the Afghan border have been put on alert to help ensure peaceful elections in neighboring Afghanistan. Pakistan's military said in a statement on Saturday that some 80-thousand troops, backed by helicopter gunships had taken positions to seal the border. Troops were also tracking suspected militants thought to be hiding in the remote North Waziristan tribal area near the border. Pakistan's army established some 760 posts along a key 600-kilometer stretch of the border to stop militants from crossing over ahead of Sunday's election. An overnight curfew has also been imposed and troops given orders to shoot on sight anyone found within five kilometers of the border.
