ISLAMABAD: Human rights advocates including Nobel Peace Prize laureate Malala Yousafzai criticised Pakistan on Wednesday for stopping a leading ethnic minority activist from travelling to accept a US award.

Mahrang Baloch, one of Pakistan’s most prominent rights voices, said officials blocked her from leaving Karachi for New York on Monday night to attend a TIME magazine awards gala.

The 31-year-old had been due to accept an award for campaigning on behalf of the Baloch ethnic group, which claims it has been targeted by Islamabad with extrajudicial harassment, arrests and killings.

“Mahrang Baloch’s activism for Baloch people should be recognised, not denied a platform,” Pakistan’s Malala Yousafzai wrote on social media platform X on Wednesday.

“I know this will not deter her from continuing to speak up and protest peacefully for human rights,” she said.

The Pakistan government says its forces are fighting separatist militants, who target state forces and foreign nationals, in southwestern Balochistan province.

Baloch said she held a valid US visa but immigration officials in Karachi prevented her from boarding her flight.

She said she was detained for five hours and that her passport and phone were seized, blaming police and the Federal Investigation Agency, a Pakistani intelligence service.

Neither organisation responded immediately to a request for comment.

“This action reflects the growing fear and insecurity of the state toward Baloch voices,” Baloch said in a video statement late on Monday.

“There was no legitimate purpose for preventing my travel, except to silence Baloch voices from being heard internationally,” she said.

Baloch, a doctor, was named on the 2024 TIME100 Next list of “rising leaders” who the magazine believes “will play an important role in leading the future”.

The Human Rights Commission of Pakistan said blocking Baloch’s travel was “a flagrant violation of her right to freedom of movement and expression”.

UN Special Rapporteur on Human Rights Defenders Mary Lawlor said on X she was “very concerned”.

Baloch began her activist career at the age of 16 in 2009, when her father went missing in an alleged “enforced disappearance”. His body was found two years later.
