Islamic State says it's behind Tunisia attack
The Islamic State group has claimed responsibility for an attack in central Tunis on an envoy carrying Tunisia's presidential guards.
In a statement posted on the Internet on Wednesday, the group says a militant it identified as Abu Abdullah al-Tunisi carried out the attack after infiltrating the bus and killing around 20 "apostates."
The statement says the "tyrants of Tunis will not have peace and we will not rest until the law of God governs in Tunis."
Tuesday's explosion killed 13 people and the president declared a month-long state of emergency after the attack.
