Afghan police say they have foiled a suicide bomb attack after they stopped a car loaded with explosives and arrested its driver.
The incident happened in the western city of Herat during a routine inspection of vehicles at a checkpoint.
The police found rockets, mines and anti-aircraft shells inside the car, an official said.
The incident comes after a bomb exploded in a car in the capital, Kabul, on Sunday. No-one was injured.
Investigators declined to say who might have been planning the alleged attack.
Interior Ministry spokesman Lutfullah Mashal said the bomb was made of rockets, mortar rounds, land mines and dynamite wired together
"It was almost 400 to 500 kilos (880 to 1,100 pounds) of explosives placed in a Toyota station wagon model 1993 and its Afghan national driver has been arrested as well," he told AFP news agency.
There has been an increase in militant activity in the south and east of Afghanistan after a lull during the winter.
