Afghan officials say a sticky bomb attached to a police vehicle went off near a campaign rally by President Ashraf Ghani in the country's northern Parwan province.
There was no immediate word of casualties in the explosion.
The president's campaign spokesman Hamed Aziz says that Ghani was there but that he is safe and unharmed. Aziz said he would provide more details later.
Wahida Shahkar, spokeswoman for the provincial governor in Parwan, says the explosion happened while the rally was underway on Tuesday, at the entrance to the venue.
No group immediately claimed responsibility for the attack.
Across Afghanistan, militant attacks have continued as the country prepares for presidential elections later this month.
MANADO, Indonesia (AP) — Indonesia's Mount Ruang volcano spewed more hot clouds on Wednesday after an eruption the previous day forced the closure of schools and airports, pelted villages with volcanic debris and prompted hundreds of people to flee.
Seven airports, including Sam Ratulangi international airport in Manado, the capital of North Sulawesi province, remained closed after Tuesday's eruption, the second in two weeks. Schools were shut to protect children from volcanic ash.
The volcano is on tiny Ruang Island, part of the Sitaro islands chain.
The Indonesian geological agency urged people to stay at least 7 kilometers (4 miles) from the volcano’s crater. It warned people on nearby Tagulandang Island, the closest to the volcano, of possible super-heated volcanic clouds from a further eruption and a tsunami if the mountain's volcanic dome collapses into the sea.
Video released by the National Search and Rescue Agency showed about a hundred villagers from Tagulandang Island being evacuated on a navy ship. Hundreds of others were waiting at a local port to be evacuated.
Agency spokesperson Abdul Muhari said 11,000 to 12,000 people living within a 7-kilometer danger zone would be taken to government shelters.
Tuesday’s eruption darkened the sky and peppered several villages with ash, grit and rocks. No casualties were reported.
After Mount Ruang's April 17 eruption, authorities warned that a subsequent eruption might collapse part of the volcano into the sea.
Ruang is among about 130 active volcanoes in Indonesia. The archipelagic nation is prone to volcanic eruptions and earthquakes because of its location on the Pacific “Ring of Fire,” a series of fault lines stretching from the western coast of the Americas through Japan and Southeast Asia.
