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.

Activists supporting the protest projected images on the wall of the embassy on August 4, prompting a police response.

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.

This footage shows British police talking to a group of people after they projected photos of Hassan Mushaima and other activists at the wall.

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. Credit: Sayed Ahmed al-Wadaei via Storyful
