A defense lawyer in Bahrain says a demonstrator has been sentenced to three months in prison for hanging a Bahrain flag from his truck during 2011 rallies.

Thursday's ruling is among the first based on tougher penalties imposed last month for insulting the Gulf state's king or national symbols. The measures seek to quell more than two years of protests led by Bahrain's majority Shiites seeking a greater political voice in the Sunni-ruled nation.

Defense lawyer Hashim Saleh says 62-year-old Abdulla al-Sayegh plans to appeal the sentence and the 100 dinar ($265) fine. Al-Sayegh acknowledges he attended pro-reform rallies during the early days of the Arab Spring uprising.

On Wednesday, six Twitter users in Bahrain were given one year each in prison for posts deemed offensive to the king.
