A car bomb exploded in a busy market in eastern Afghanistan on Tuesday, killing at least 38 people and wounding 30 others, police said.

The car was driven by a suicide bomber who detonated explosives after police ordered him to stop his car, said Nissar Ahmad Abdulrahimzai, deputy police chief of Paktika province.

Meanwhile, in the capital, Kabul, the Taliban claimed responsibility for an attack early Tuesday on a vehicle used by presidential palace employees.

Taliban spokesman Zabihullah Mujahid said in a statement to media that three people were killed and six others injured in the explosion. He said all the victims were working in the presidential palace media department.
