Bahraini protestors take cover behind a shield during clashes with riot police on April 3, 2014 in the village of Al-Akr, south of the capital Manama, after the funeral of Hussein Ahmed Sharaf, a Bahraini man who was in hiding having earlier been sentenced to life in prison in absentia, following his death in an explosion at his home two days ago. Bahrain tightened security, as the three-day Formula One Grand Prix was about to get underway, with the country's Shiite opposition planning protests to seize world attention for pro-reform demands.
