A Bahraini court jailed six people for a year on Wednesday for insulting King Hamad bin Isa al-Khalifa in messages on Twitter, the official news agency said. The six were accused of posting remarks “undermining the values and traditions of Bahrain’s society towards the king on Twitter,” the head of the public prosecutor’s office, Nayef Youssef, said in a statement reported by the Bahrain News Agency. He said freedom of opinion and expression were guaranteed by the Constitution, law and international conventions, but should not be used in a way that contradicted the norms of society. The news agency gave no further information about the six.
