A court in Egypt has handed down two-year jail sentences to 12 supporters of ousted President Mohamed Morsi and the Muslim Brotherhood movement over alleged roles in violence.

The court on Saturday accused the 12 of being involved in violence, which included street clashes, attempted murder and battery charges, in the seaport city of Suez in December 2013. It acquitted six others in the case.

Egypt banned Muslim Brotherhood in December 2013. The ban came five months after the army removed Morsi, the first democratically-elected president of Egypt, in July of that same year.

The military has also launched a heavy-handed crackdown on the opposition and repressed freedom of speech in the Arab country.

On June 1, a military court in the Nile Delta province of Monoufiya sentenced 71 anti-government protesters to jail, in terms ranging from two to seven years.

Separately, a criminal court in the capital, Cairo, handed down jail terms ranging from five to 10 years to 29 anti-government protesters.

On May 18, an Egyptian court sentenced Morsi to death on charges of endangering national security. The final ruling on Morsi’s preliminary death sentence is set to be announced on June 16.
