(International Business Times) Islamic State (Isis) has claimed responsibility for a suicide bombing in Saudi Arabia's eastern province that killed over 20 people while they prayed at a local mosque. The bombing marks the first time IS has struck inside Saudi Arabia.
The jihadi group has issued a statement in Arabic on Twitter as well as what appears to be a photograph of the bomber, who targeted a Shi'ite mosque in the village of al-Qadeeh.
The village is in the restive Shi'ite province of Qatif, which has seen rising tensions between Shi'ite residents and nearby Sunni tribes as well as with the Saudi Arabian government.
