The Baghdad suicide attack
ISIS responsible for attack?
Even though no one has claimed responsibility for the attack yet, authorities say it is the handiwork of ISIS militants.
ISIS has begun losing its grip on Iraq since the government troops began their offensive to drive the militants out.
Officials said this was their tactic to show that their presence was still strong within the country.
ISIS returning to insurgent roots?
Analysts said that since they have been losing territory at such an alarming rate, ISIS will most likely return to its insurgent roots, carrying out isolated bombings and attacks in Iraq and Syria.
