AQAP

Despite occasional Saudi claims of fighting terrorism, AQAP has actually gained territory while the coalition and pro-Hadi forces have concentrated on the Houthis

Pro-Hadi forces

Abd Rabbuh Mansur Hadi was elected unopposed in 2012 to aid transition from the violent end of Saleh’s regime but he failed to strengthen the failing state, which the Houthis and al-Qaida in the Arabian Peninsula (AQAP) exploited

Houthis

The rebels belong to the Zaydi sect of Shia Islam, long excluded by Sana’a elites. The extent of Iran’s backing is disputed, but they do have the support of forces loyal to former president Saleh
