Ali Mushaima, the son of a prominent opposition figure jailed in Bahrain, has been on hunger strike outside the Bahraini embassy in London since August 1.Mushaima has demanded medical care for his 70-year-old father, Hassan Mushaima, and accused the Bahraini authorities of refusing treatment. He has also asked for family visits and the delivery of books to his father to be allowed.Amnesty International said in a statement released on August 6 that Bahraini authorities “deliberately denied proper medical care for four elderly jailed activists, Hassan Mshaima, Abdel-Jalil al-Singace, Abdel-Wahab Hussain and Abdel-Jalil al-Miqdad, subjecting them to cruel, inhuman and degrading treatment and putting their lives at risk.”The four were sentenced to life imprisonment in 2011, Amnesty said.This footage shows Ali Mushaima protesting outside the Bahraini embassy in London.
