In this Friday, August 9, 2019, file photo, Pakistan Rangers soldiers face Indian Border Security Force soldiers at a daily closing ceremony on the Indian side of the Attari-Wagah border. India's recent clampdown has a long history in Kashmir and the conflict has existed since the late 1940s, when India and Pakistan won independence from the British empire and began fighting over rival claims to the Muslim-majority territory. India and Pakistan have fought two of their three subsequent wars over Kashmir, and each administers a portion of the region. India has long seen the Kashmiri struggle for self-determination as Islamabad's proxy war against New Delhi. (Photo by Prabhjot Gill/AP Photo/File)

A Gnawa traditional group performs in the city of Essaouira on December 14, 2019, to celebrate the decision of adding the Gnawa culture to UNESCO's list of Intangible Cultural Heritage of Humanity. Gnawa culture, a centuries-old Moroccan practice rooted in music, African rituals and Sufi traditions, was added to UNESCO's list of Intangible Cultural Heritage of Humanity earlier in the week. Gnawa refers to a “set of musical productions, fraternal practices and therapeutic rituals where the secular mixes with the sacred”, according to the nomination submitted by Morocco. Often dressed in colourful outfits, Gnawa musicians play the guenbri, a type of lute with three strings, accompanied by steel castanets called krakebs. (Photo by Fadel Senna/AFP Photo)
