The International Women's Day march has has faced condemnation from the religious parties for making 'indecent' demands.
The first such march was organised in 2018 in Islamabad and Lahore.
Women in Pakistan are demanding access to public spaces, more representation at work, freedom to wear clothes of their own choice and more rights over their properties.
Stating these demands to be against the Islamic culture, extreme religious parties including Ahle Sunnat Wal Jamaat and Jamaat-e-Islami demonstrated in Islamabad, claiming women don't need rights over their own bodies.
The marches in other cities were concluded peacefully. In Lahore city, a resolution condemning under-age marriages and demanding that women be granted legal, social and economic protection was submitted in the Punjab Assembly.
