Candidates jockeying to become Afghanistan's next president lashed out at the incumbent Ashraf Ghani on Monday after deadly violence cast a shadow over the first official day of campaigning.
 At least 20 people -- most of them civilians -- were killed and 50 others wounded Sunday when a suicide attacker and gunmen targeted the Kabul office of Ghani's running mate, Amrullah Saleh.
The violence served as a grim reminder of Afghanistan's woeful security situation and the sort of mayhem and murder that have beset previous polls. | |
