Bahraini police killed a 16-year-old Shiite on Friday as security forces attempted to prevent protesters from joining weekly prayers called for by the opposition, Al-Wefaq group said.
Ali Radhi was killed as he headed to the village of Diraz, west of Manama, to attend prayers led by Shiite spiritual leader Sheikh Issa Qassim, answering a call by Al-Wefaq, the main Shiite opposition formation said on its Twitter page.
It was not immediately clear how Radhi was killed, but the opposition said police used tear gas against the worshippers.
Al-Wefaq posted pictures on Facebook and Twitter showing worshippers trying to reach Diraz as police allegedly blocked the roads leading to the Shiite village.
Elderly people can be seen in the pictures collapsed on the ground after allegedly being targeted with tear gas.
