A teen died in clashes in Bahrain as protesters hit the streets Thursday on the two-year anniversary of a failed uprising in the nation, authorities said.

Authorities are investigating the Thursday morning death of a 16-year-old teen and trying to determine how it occurred, according to a government statement.

Al-Wefaq, Bahrain's main Shiite opposition party, said the teen was killed when he was hit by bird pellets shot by Bahraini security forces.
