Afghan crisis: Ashraf Ghani sworn in as President, Abdullah also declare himself President

Kabul: Afghan challenger Abdullah Abdullah inaugurated himself as president Monday, minutes after the incumbent Ashraf Ghani was sworn into office for a second term, deepening a political crisis that has stoked fears for upcoming peace talks with a strong Taliban.

Ghani was declared as the winner of the election held last September, but Abdullah, who disputed the vote, held a parallel ceremony surrounded by hundreds of supporters during which he vowed to "safeguard the independence, national sovereignty, territorial integrity" of Afghanistan.

Meanwhile, two blasts were heard as Afghanistan's two rival leaders held parallel presidential inaugurations in Kabul, underscoring the country's woeful security ahead of talks with a resurgent Taliban. Hundreds of people had assembled at two venues inside the presidential palace complex to watch the swearing-in ceremonies for President Ghani and challenger Abdullah Abdullah, when the blasts were heard, prompting some to flee.

"I have no bulletproof vest on, only my shirt, I will stay even if I have to sacrifice my head," Ghani told the remaining crowd, as sirens sounded overhead.

Polls were held in September but incumbent Ashraf Ghani was only declared to have won a second term in February after repeated delays and accusations of voter fraud, sparking a furious response by former chief executive Abdullah Abdullah, who vowed to form his own parallel government.

Last-minute talks reportedly extended late into the night Sunday as the two sides sought to broker an agreement.

But by Monday morning, there was little indication a solution had been found, with Ghani's spokesman only announcing that his inauguration would be delayed by several hours.

Abdullah also postponed his ceremony until the afternoon, with a member of his campaign staff telling supporters that if Ghani proceeded "with his inauguration, we will definitely go ahead with ours".

Washington had earlier warned that the bickering posed a risk to the US withdrawal deal, which requires the Taliban to hold talks with Kabul.

Widening divisions among Afghan politicians would leave the insurgents with the upper hand in those negotiations.

Their game of thrones has left many Afghans despairing for their country's future.

"It is impossible to have two presidents in one country," said Ahmad Jawed, 22, who urged the men "to put their personal interests aside and only think of their country instead of fighting for power".

He told AFP that "instead of holding oath-taking ceremonies they should talk to each other to find a solution".
