Oct 15 (Reuters) - Iraq's parliament on Thursday approved the remainder of Prime Minister Alial-Zaidi's cabinet, completing the formation of a government that took office five months ago with several key positions, lawmakers said.

• Lawmakers approved 11 portfolios, includingNayef al-Shammari as defence minister and Yasir al-Maliki as interior minister

• Positions had been vacant since Zaidi's government took office in May

• Parliament postponed votes on the nominee for migration and displacement minister due to disagreement among parties, lawmakers said

• Lawmakers also approved threedeputy prime ministers, including Laith al-Khazali, a senior leader of the Iran-backed Asaib Ahl al-Haq movement

• The US in 2020 designated Asaib Ahl al-Haq as a foreign terrorist organisation and its leaders, brothers Qais al-Khazali and Laith al-Khazali, as specially designated global terrorists

• The US has accused the group of carrying out attacks against US and coalition forces in Iraq

• Zaidi's government programme pledged economic reforms, anti-corruption measures and efforts to strengthen state institutions

• But it faces significant challenges, including rebuilding an economy hit by regional instability, tackling endemic corruption, and bringing Iran-allied armed groups under greater state control
