About 30 people were inside the building when the explosion occurred, according to a temple official.
A blast has hit a Sikh temple in the Afghan capital, Kabul, a temple official said, but it was unclear if there were casualties.
“There were around 30 people inside the temple. We don’t know how many of them are alive or how many dead. The Taliban are not allowing us to go inside, we don’t know what to do,” Gornam Singh, a Sikh community leader, told news agencies on Saturday.
“I heard gunshots and blasts coming from the gurdwara,” Singh said
Taliban officials have not confirmed the explosion, and it was not immediately clear who was behind it.
Local broadcaster Tolo aired footage showing heavy grey fumes of smoke rising from the area.
Afghanistan’s Taliban rulers say they have secured the country since taking power in August, but international officials and analysts say the risk of a resurgence in violence remains.
Multiple attacks have taken place in recent months, with some claimed by the ISIL (ISIS) group.
Sikhs are a tiny religious minority in largely Muslim Afghanistan, comprising about 300 family members before the fall of the country to the Taliban. Many had left the country in the wake of the takeover, according to community members and media reports.
The Sikh community, like other religious minorities, has been the continual target of violence in Afghanistan. An attack claimed by ISIL at another temple in Kabul in 2020 killed 25.
Faiz Zaland, a professor of political science at Kabul University, told Al Jazeera that the Taliban is struggling to deal with internal security threats in the country.
“The Taliban are lacking counterterrorism and counterinsurgency [skills]. They also lack regional and international intel sharing support,” Zaland said.
“The groups carrying out these attacks are sending message to the government to say that [the Taliban] do not have control over the population’s security and cannot protect the minorities. This creates a trust deficit,” he added.
Saturday’s explosion follows a blast on Friday in the northern city of Kunduz at a mosque that killed one and injured two, according to authorities.
Last month, a similar attack at a mosque in the capital, Kabul, killed at least five people and wounded 22.
In April, a powerful explosion ripped through Khalifa Aga Gul Jan Mosque – also in Kabul – during Friday prayers, killing at least 10 people and wounding as many as 30.
