(CNN) -- Government forces attacked protesters in Bahrain Saturday, according to a human rights group."Security forces have spent the day attacking protests in different parts of the country," the Bahrain Center for Human Rights said in a statement. "Many serious injuries were reported, including a 15-year-old boy who was hit directly in the arm with a teargas canister."
The group also said its president, Nabeel Rajab, was arrested before a planned march in Manama that was to be a show of solidarity with Abdulhadi Al-Khawaja, one of Bahrain's most prominent human rights activists.
Al-Khawaja was sentenced to life in prison in June for his role in the anti-government demonstrations that swept through Bahrain a year ago. He has been on hunger strike for more than 50 days in protest of his sentence.
On Friday, Amnesty International issued a statement calling on Bahraini authorities to release al-Khawaja amid fears that he is at risk of death. Read More
