The Taliban, an Islamist group that believes in Sharia law, formed a Government after its resurgence in Afghanistan in August and September following the withdrawal of American troops and the collapse of the Western-backed administration led by President Ashraf Ghani.

It vigorously restricts the freedoms of women and does not believe in female sport. 

Despite this, Yasamin Azizi has continued training her students, though the number has dropped dramatically.

"It has been two or three months since the previous Government collapsed and we train secretly in different gyms, and as you all know, that girls are not allowed to resume their activities or training, but I still do my best to serve my society, especially those girls who are addicted to exercise," said Azizi in a news report published by Reuters on YouTube.

Azizi has been a member of Afghanistan's national taekwondo team for six years and used to train 60-70 female athletes under the Ghani-led Government.

One of her trainees, Behtareen Rostaee, provided an insight into what life is like under Taliban rule.

"Three days ago some of our gym partners who are also members of the national taekwondo team were pursued by the Taliban all the way to their homes," said Rostaee.

"The Taliban even went inside their homes for inquiries. 

"This is really hard for us, that we can neither resume our education nor can we continue our training."

When the Taliban were last in power between 1996 and 2001, women were barred from partaking in sport, employment and education.

The unrest in Afghanistan comes after the sports community aided many athletes fleeing the country.

However, International Olympic Committee President Thomas Bach has called on National Olympic Committees (NOCs) to do more.

"There are still many members of the community in Afghanistan who are at risk, because they are members of our community, we have to and we will help them," Bach said at the ANOC General Assembly.

"But we need for this the support of as many as possible Governments and NOCs, because we have two challenges - first of all, we need to get them out of the country.

"It is about seats on airplanes, about land routes and other options and alternatives.

"We can only get them out in many cases that we can give the assurance they are welcomed by humanitarian visas in countries.

"First of all I have to thank you, but I would also like to urge those who have already community to continue helping and assisting.

"Please seize this opportunity, try to convince them to get humanitarian visas for members of the Olympic community in Afghanistan and community to safe places."
