Islamic State Takes Responsibility for Yemen Mosque Attack

More than 100 people were killed in Yemen's capital on Friday when suicide bombers carried out attacks on two mosques. The Islamic State terror group has claimed responsibility for the attacks.

The attacks happened Friday morning at two Shiite temples in Yemen's capital of Sana, killing 130 people. The mosques were attended by members of the Zaydi Shiite group, who are members of the Houthi rebel group, which controls the capital.

According to The New York Times, Sunni extremists, including members of the Islamic State and groups affiliated with al-Qaeda, consider the local ruling Shiite group to be heretics.

The Islamic State, which has a branch of its terrorist group in Yemen, took responsibility for the attacks on Twitter. The terrorist group posted about the attack, describing the Houthis as "polytheists" and said the recent attack was "but the tip of the iceberg that is coming."

"This operation is but the tip of the iceberg," the group said in an audio message posted on jihadi blogs and on Twitter. "Let the polytheist Houthis know that the soldiers of the Islamic State will not rest and will not stay still until they extirpate them."

The Islamic State also took responsibility for a recent museum attack in Tunisia's capital that left 23 dead. Many of the tourists killed in the attack were from foreign countries.

Mohamed Abdulsalam, a Houthi spokesperson, spoke out against Friday's attack saying in a statement: "We will confront the increasing threats with great courage."

"We will continue to escalate and go forward with the remaining steps in our revolution to defend the Yemeni people and their esteemed revolution," the statement added.
