An American pastor has been kidnapped by armed men after they stormed his church service in South Africa, local authorities say.

Josh Sullivan had been conducting a service at Fellowship Baptist Church in Motherwell, a township in Gqeberra in the Eastern Cape, on Thursday evening when “four armed and masked male suspects entered”, police spokesman Captain Andre Beetge told the BBC.

The men stole two phones before fleeing the church in the 45-year-old pastor’s silver Toyota Fortuner. Police later found the vehicle abandoned, but there was no trace of Mr Sullivan.

A spokesperson from the US State Department told the BBC that they were aware of the kidnapping of a US citizen in South Africa.

They said there was no “greater priority than the safety and security of US citizens abroad”.

Capt Beetge told the BBC the case had been handed to South Africa’s elite police unit, known as the Hawks, which investigates serious organised and commercial crimes and high-level corruption.

“The police is currently following all possible leads to locate the victim and apprehend the perpetrators,” said Hawks spokesman Lt Col Avele Fumba.

Jeremy Hall, the Sullivan family’s spokesman, told local newspaper TimesLive that he was at the church with his wife and their children when the incident took place.

“They knew his name,” he said.

Mr Sullivan’s mother, Tonya Morton Rinker, wrote on Facebook that she was heartbroken over the news.

She added: “Our congressman and American embassy are working on finding him.”

No ransom has been requested, according to the privately-owned News24.

Mr Sullivan describes himself as “a church planting missionary” on his personal website.

On it, he says he moved to South Africa with his wife and children in 2018 to establish a church for Xhosa-speaking people.

Over the past decade, there has been 264% increase in kidnappings in South Africa, according to police statistics.

Just a few days ago, a Chinese national was kidnapped in Gqberra.
