Yemeni police forces arrested eight terrorists linked to the Daesh group, according to a statement issued on Tuesday by Aden Police.

Anti-terrorism soldiers conducted an overnight operation, busting the terrorist cell, responsible for a series of drive-by assassinations and attacks in the port city of Aden, and storming several locations in the province of Aden.

Silent pistols, letters, and various jihadist leaflets, sent to the terrorist militants from Daesh leaders in Iraq and Syria were seized from the raided houses, the police statement said.

The southern port city of Aden is the headquarters of Yemen's internationally-backed President, Abdu-Rabbu Mansour Hadi and his government.

Aden witnessed several well-planned assassinations and armed attacks, after Saudi-backed forces drove the Shiite Houthi rebels out from the strategic city in July, 2015.

However, the newly-trained anti-terrorism troops, supported by UAE armoured vehicles, made substantial achievements in recent weeks, disabling several explosive material factories used by terrorists to manufacture car bombs in Aden.

In addition, several commanders of the Yemen-based al-Qaeda branch were captured, in the successful raids conducted by the UAE-backed Yemeni forces in Aden and neighbouring provinces.

Yemen, an impoverished Arab country, has been gripped by one of the most active regional Al-Qaeda insurgencies in the Middle East.

The Yemen-based Al-Qaeda in the Arabian Peninsula (AQAP), also known locally as "Ansar al-Sharia," emerged in Jan, 2009, claiming responsibility for a number of terrorist attacks against Yemen's army and government institutions.

The AQAP and the Daesh-linked terrorists took advantage of the security vacuum and ongoing civil war to expand their influence and seize more territories in southern Yemen.
