Campaigning is officially underway for Afghanistan's presidential election, with 11 candidates vying to succeed President Hamid Karzai.
The April 5 presidential vote will be a crucial test of whether Afghanistan can ensure a stable political transition as NATO combat forces ready their withdrawal after nearly 13 years of war.
The election faces many hurdles: allegations of vote-rigging marred the 2009 election and security is a major concern.
The specter of violence hangs over the campaign, with the Taliban vowing to disrupt the poll. On the eve of the campaign launch, two political workers were killed in western Afghanistan.(AP)
