Taliban suicide attackers killed at least 24 people in Afghanistan on Tuesday (September 17), their deadliest bombing taking place near an election rally by President Ashraf Ghani, although he was unhurt.

Reports say Ghani, who is seeking a second five-year term in voting on Sept. 28, was due to address a rally in Charikar, the capital of central Parwan province, when a bomber attacked the gathering.

The blast killed 24 people and wounded 31, said Abdul Qasim Sangin, head of Parwan’s provincial hospital.

Meanwhile, a blast in the center of Afghanistan’s capital Kabul killed at least six people this Tuesday (September 17), police officials said, in a bombing also claimed by the Taliban.

The attacks happened 11 days before Afghanistan’s presidential elections, which Taliban commanders have vowed to violently disrupt, and follow collapsed peace talks between the United States and the insurgent group.
