Several Shia religious gatherings and centers have come under attack in Bahrain and neighboring Saudi Arabia in recent months.
The developments also come as there has been a wave of extensive arrests in Bahrain in the wake of protests in condemnation of the execution of 47 people in Saudi Arabia including prominent Shia cleric Sheikh Nimr al-Nimr. Bahrain, like several other Muslim countries, saw demonstrations in solidarity with the families of the executed people.
Since March 2011, Bahrainis began to take to the streets to demand a change in the political system. The regime in Manama responded with a heavy-handed crackdown by killing dozens and arresting hundreds of people, including notable opposition leaders.
