ISIS has claimed responsibility for a car bomb that killed at least 13 people and wounded about 30 in the early hours of Tuesday in a commercial street of central Baghdad, according to security sources.

Axar.az reports citing Yeni Safak.

The bombing targeted the Karrada district, which was hit by a massive truck bomb in July 2016 that killed at least 324 people, the deadliest attack in Iraq since the U.S.-led invasion of the country in 2003.

The 2016 blast was also claimed by ISIS.

Both bombings happened during the Muslim holy month of Ramadan, during which people stay up late and many eat out to prepare for the fast the next day.

ISIS's Amaq news agency claimed Tuesday's attack in Karrada, a mainly Shi'ite Muslim district.

The terrorist group has been retreating in Iraq since the end of 2015 in the face of U.S.-backed government forces and Iranian-backed Shi'ite paramilitary groups.

It is now besieged in an enclave in the northern city of Mosul, which it has used as its de facto capital in Iraq.
