Sana’a: The Al Houthis, who control much of Yemen, have removed the air force chief for refusing to provide them with air support and replaced him with a general who is closer to their group, military officials said.

The move shines a light on the divisions in Yemen’s shattered military as the Iran-backed Al Houthis and embattled President Abd Rabbo Mansour Hadi vie for control.

Hadi fled Al Houthi house arrest last month and re-established his presidency in the southern port of Aden, while the Al Houthis control Sana’a. The United Nations, which is brokering talks between the two sides, has warned of imminent civil war.

Major General Rashid Al Jund along with the air force’s chief of staff was dismissed on Monday and placed under investigation by the Supreme Security Council, a body formed by the Al Houthis after they seized Sana’a, the military sources said.

He was replaced by Brigadier General Khader Salem, whom the officials said was more sympathetic to the Al Houthis.

Al Houthi officials did not immediately respond to requests for a comment.

The advance of the group into the capital in September and to other regions, mainly in central and eastern Yemen, has been met with resistance from armed Sunni tribes, some of whom are backed by al Qaeda militants.

Dozens from both sides have died in fighting for the central

province of Al Bayda, and the Al Houthis have been targeted by bombings of Islamist militants, including Al Qaida, who consider the Al Houthis heretics.

The strong Al Qaida presence in Yemen makes it an international security concern, particularly as it borders on top oil exporter Saudi Arabia and major shipping lanes.

While the Al Houthis say they are waging a revolution against corrupt officials and their lackeys, Yemen’s powerful Gulf Arab neighbours call their takeover a coup supported by Iran. Tehran denies backing the Al Houthis.
