A Bahrain court today [March 15, 2015] postponed its verdict in an appeal made by leading Bahraini human rights defender Nabeel Rajab against a six-month prison sentence until April 15.

The case concerns comments he made about ISIS on Twitter. Rajab was initially convicted of “denigrating an official body” in tweets that likened Bahrain's security apparatus to an “incubator” for fighters of the radical group ISIS.

Rajab, who heads the Bahrain Centre for Human Rights — not recognised as a legal entity by the government — was only released from prison in May 2014 after serving two years for “disrupting the public order.”

That sentence came after Rajab was arrested for trying to investigate human rights violations that took place during Bahrain's popular uprising in 2011.

The tweet for which he was convicted suggested that Bahrain's security institutions had a number of staff that had joined terrorist groups, including ISIS.

Following today's hearing, Rajab tweeted to his 260K followers on Twitter:
