UPDATE:

The Islamic State (IS) claimed credit for the raid on the Bardo Museum in the Tunisian capital, Tunis, and warned that the attack is the "first drop of the rain." The group identified the attackers as Abu Zakaria al-Tunisi and Abu Anas al-Tunisi.

The Tehrik-e-Taliban Pakistan (TTP) offshoot Jamat-ul-Ahrar claimed credit for suicide bombings on two churches in Lahore, Pakistan. Ehsanullah Ehsan, the group’s spokesman, tweeted the claim on March 15 and stated that it had been carried out by the group’s “Aafia Siddique Brigade.”

The recent Islamic State (IS) suicide bombing in Ramadi, Iraq by "Abu Abdullah al-Australi," the alias of Australian teenager Jake Bilardi, has brought shock to Australia and other Western countries. However, news of Bilardi's suicide mission may be less surprising considering the past year of Western-aimed propaganda from IS—much of which specifically directed at Australia.

The Islamic State (IS) released a video showing the execution of Mohammad Said Ismail Musallam, a Palestinian hostage who allegedly confessed to being "an agent for the Israeli Mossad."

Twitter accounts of Islamic State (IS) fighters and supporters offered welcoming messages to the Nigeria-based jihadist group Jama’at Ahl al-Sunnah Lil Dawa Wal Jihad (AKA Boko Haram) after its leader, Abu Bakr Shekau, recently pledged allegiance to IS leader Abu Bakr al-Baghdadi. These celebratory messages were also made in bragging fashions, projecting what the users claimed to be IS’s rapidly expanding global network.
