Al Jazeera correspondent Imran Khan looks at the conflicts that led to millions fleeing their homes in the Middle East.
Bombings in Baghdad have killed at least 10 people and wounded at least 55, Iraqi security and medical officials say.
Thursday’s twin attacks were carried out by bombers on foot, wearing explosives-laden vests, two police officers said.
One bomber struck in Baghdad’s Bab al-Sharji area. The second struck at al-Wathba Square.
The Islamic State of Iraq and the Levant (ISIL) group claimed responsibility on Thursday for the bomb attacks.
In a statement posted online, ISIL said two fighters had targeted police and Shia militia fighters.
ISIL overran swaths of the country in June last year. Iraqi forces backed by a US-led coalition and Iran have since managed to regain significant ground north of Baghdad from ISIL, but much of western Iraq remains outside government control.
Since the emergence of ISIL, Baghdad has seen near-daily attacks, with roadside bombs, suicide blasts and assassinations targeting Iraqi forces and government officials, with significant casualties among the civilian population.
The violence has killed hundreds and displaced tens of thousands of Iraqis.
