BAGHDAD (AP) — Iraq’s parliament officially named Haider al-Abadi the country’s new prime minister late Monday and approved most of his proposed Cabinet amid calls by the Arab League for its members to combat the Sunni militant group violently advancing across Iraq and Syria.

Lawmakers approved all of the candidates proposed for Iraq’s new government, with the exception of a few posts, namely the defense and interior ministers. Al-Abadi requested an additional week to name them.
