According to security officials, at least 11 people lost their lives and over 30 others were wounded after two bombers blew up their explosives-laden vehicles on Friday at checkpoints near a military base as well as a highway near the area's oilfields.
Seven of the injured are reportedly in critical condition.
The first blast occurred outside the Ar-Rumeila military base, where eight people were killed, including the head of the local intelligence establishment as well as a number of intelligence forces, according to the sources cited in local reports.
Confirming the first bombing, Basra operational commander, Jameel al-Shemri, further announced in a news briefing that a second bomber also blew up his explosives-packed vehicle near the al-Sadra checkpoint on a highway leading to the region's oilfields.
The attacker then detonated his explosive vest after he was surrounded by security force, killing three people.
This is while the southern province of Basra, where the bulk of the nation's oil is produced, remains one of the most stable and secure regions of Iraq, in which bomb attacks are quite rare.
