Bahrain has been witnessing almost daily protests since mid-February 2011 against the ruling Al Khalifa dynasty as uprisings began in the Middle East, with security forces in the Persian Gulf country using heavy-handed measures to crack down on protesters.
Scores of Bahrainis have been killed and hundreds of others injured and arrested in the ongoing crackdown on the peaceful demonstrations.
