The United Arab Emirates has said that one of its warplane taking part in a mission against Houthi rebels in Yemen is missing.
The country’s official news agency, WAM, announced the disappearance without giving further details.
The Saudi-led coalition of which UAE is a part has been carrying out airstrikes in Yemen since March 2015 in support of President Abedrabbo Mansour Hadi.
Some 6,000 people have been killed in the Yemen conflict.
It is the first known loss of an Emirati jet in the conflict.
In December, a Bahraini F-16 crashed in Saudi Arabia due to a “technical error”, while in May a Moroccan warplane came down over Yemen.
Both jets were taking part in the Yemen campaign, which has the codename “Operation Decisive Storm”
