A bomb attack in Bahrain's mainly Shi'ite village of Sitra, south of the capital Manama, has killed two policemen and wounded 8 others. The country's Interior Ministry said in Arabic on Twitter that the blast was a "terrorist attack" but did not specify which group was responsible. Then, it posted a statement in English:

Sectarian tensions have increased in Sunni-ruled Gulf countries after Islamic State (Isis) militants claimed responsibility for three bombings of Shi'ite mosques in Saudi Arabia and Kuwait. After the crackdown on the pro-democracy uprising in 2011, led by Saudi forces, Bahrain has plunged deeper into sectarian conflict between the wealthy ruling Sunni-al-Khalifa minority and the Shia majority.

King Sheikh Hamad bin Isa Al-Khalifa has pledged to implement recommendations by an independent commission of inquiry but reforms are progressing slowly and reconciliation talks have stalled. Violence between riot police and protesters is a weekly occurrence. Recently, Bahrain's human rights activist Nabeel Rajab, who had been jailed on charges of publicly "insulting a public institution" on Twitter, was granted a royal pardon for health reasons and freed.
