Viagra bought 'for altitude sickness'

Blue House says pills purchased for presidential aides and employees on Park's May trip to Africa 'left unused'

The office of South Korean President Park Geun-hye said on Wednesday it had bought dozens of Viagra pills while preparing for her trip to Africa this year, not for anyone's erectile dysfunction but to treat possible altitude sickness.

News of the purchase, confirmed by Park's spokesman, Jung Youn-kuk, came as Park is fighting calls for her to step down over allegations that she and a friend had improperly pressured big businesses to contribute funds to foundations set up to support her policy.
