Two blasts were heard as Afghanistan's two rival leaders held parallel presidential inaugurations in Kabul on Monday, underscoring the country's woeful security ahead of talks with a resurgent Taliban, EDNews reports citing TRT

Hundreds of people had assembled at two venues inside the presidential palace complex to watch the swearing-in ceremonies for President Ashraf 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.

Squabbling Afghan presidential rivals threatened to both declare themselves president in duelling inauguration ceremonies Monday, throwing plans for negotiations with the Taliban into chaos.

Those talks among Afghans on both sides of the conflict were supposed to be the next crucial step in a US-Taliban peace deal, signed less than two weeks ago. 

But the dispute between the top two candidates in last year's presidential election over who actually won means the Afghan government side appears unable to present a united front.

When Washington and the Taliban insurgents signed the deal, the promise was that Afghans would sit down and negotiate a road map for their country's future.

They are looking to hammer out such thorny issues as women's rights, free speech and the fate of tens of thousands of armed men on both sides of the 18-year war. Those negotiations were set to be held Tuesday in Oslo.

The US has said its troop withdrawal from Afghanistan will be linked to the Taliban keeping their counter-terrorism promises, but not to the success of talks between the Taliban and the Afghan government.
