War forced these people to flee from their homes

The relationship between the governments of Iran and Iraq briefly improved in 1978, when Iranian agents in Iraq discovered plans for a pro-Soviet coup d'état against Iraq's government. When informed of this plot, Saddam ordered the execution of dozens of his army's officers and in a sign of reconciliation, expelled Ruhollah Khomeini, an exiled leader of clerical opposition to the Shah, from Iraq. Despite this, Saddam merely considered the Algiers Agreement to be a truce, rather than a definite settlement, and waited for an opportunity to contest it.
