At least 13 people have been killed in a huge explosion near a mining town in south-western Ghana, officials say.
A truck carrying explosives to a gold mine crashed with a motorcycle near the town of Bogoso, according to police.
The BBC's Thomas Naadi says Thursday's explosion ripped apart the nearby village of Apiatse.
On Friday, rescue workers were still searching through the rubble for victims, while the smell of dead bodies filled the air, he says.
Many houses have been completely flattened, leaving at least 380 people without shelter.
"It's almost like a ghost town," Sedzi Sadzi Amedonu, a senior official from the country's disaster management agency, told the AFP news agency.
The impact of the explosion has left a crater on the major highway, forcing the police to divert traffic, our reporter says.
Many houses were destroyed in the blast
Local police commander William Jabialu said the number of confirmed deaths had been revised down to 13 from a previous toll of 17.
He said another 45 were being treated in local hospitals.
Among them is Grace Morgan, a 32-year-old pregnant woman, who had metal shrapnel buried deep in her left thigh.
She told the BBC she just had time to remove a gas cylinder and a gallon of petrol from her shop before she heard the explosion, saw the next shop on fire and then lost consciousness.
The truck was carrying explosives to the Chirano gold mine about 140km (87 miles) from the scene of the blast, when it was hit by a motorcycle, police say.
This reportedly caused a fire, leading to the explosion about 15 minutes later.
The driver of the truck managed to escape the blast with minor injuries, according to our reporter.
He warned residents to flee, which helped save many lives including schoolchildren.
A police officer onboard the truck also survived, but the motorcycle rider was killed.
Ghana's President Nana Akufo-Addo said the military had joined emergency efforts to help "contain the situation", and "rapid relief" was being sent to residents.
"It is a truly sad, unfortunate and tragic incident," he tweeted.
People have been told to move out of the area and police called on nearby towns to "open up their classrooms, churches etc to accommodate surviving victims".
"We continue to urge the public to remain calm as we manage the situation."
A team of police and army explosion experts were deployed to "avoid a second explosion" and secure the scene, the government said.
Although the authorities say correct transportation procedures were followed, an investigation into the circumstances of the explosion has begun.
The tragedy has raised questions about safety measures when explosives are transported on Ghana's busy roads.
