Just days after U.S. Secretary of State John Kerry brokered a political agreement in Afghanistan's contested presidential elections, a series of attacks killed nearly 100 people across the country.

One particularly gruesome attack, a car bomb in eastern Afghanistan, reportedly killed 89 people and wounded scores when a suicide bomber packed a van with explosives and detonated it near a busy market in Paktika.

According to Defense Ministry spokesman Gen. Mohammad Zahir Azimi, the powerful bomb destroyed 20 shops and dozens of cars. The attack came just hours after a roadside bomb in eastern Kabul ripped through a van carrying staffers to the palace.

The explosion struck as the vehicle was taking the palace staffers, said Gul Agha Hashimi, the chief of criminal investigations with the Kabul police. There were seven government employees on board, all from the palace's media office."

These two attacks are the first major incidents of violence since Kerry made his surprise trip to Kabul to help broker a standoff between former Finance Minister Ashraf Ghani Ahmadzai and former Foreign Minister Abdullah Abdullah, both of whom claimed victory in last month's presidential run-off.

The two are reportedly set to meet later today to work out a framework for the new government.
