Authorities in Yemen announced a curfew on the southern port city of Aden, after the city’s security committee held an emergency meeting on Sunday in an attempt to push back against recent invasions by Al Qaeda and branches of DAESH terrorist group, the city's governor said.
The curfew will start at 8pm (1700 GMT) on Monday and last till 5am (0200 GMT) for an unspecified period, according to the Aden governor, Aidarous al Zubaidi.
The curfew was imposed after heavy clashes left at least 22 people dead in Aden on Sunday, including ten members of the security forces, AFP cited pro-government media and security sources.
They said the battle began when forces loyal to President Abedrabbo Mansour Hadi met resistance, as they tried to deploy the port to secure it completely.
The security sources said that the fierce battles went on for several hours and that government forces eventually managed to take control of the port.
Suspected DAESH terrorists also shot dead Sheikh Ali Othman al Gailani, a Sufi imam who was considered a moderate after he left a mosque in the city's Crater district, witnesses said.
No group claimed immediate responsibility for the attack, but DAESH and Al Qaeda oppose Sufi schools and have in the past attacked its members in other places in the Middle East.
Meanwhile, a Saudi-led coalition carried out air strikes in the Yemeni capital Sanaa, which is held by Iranian-backed Houthi rebels, after it had declared the end of a ceasefire on Saturday.
Yemen is one of the poorest countries in the Arabian Peninsula, which plunged into conflict in 2014 when the Houthis seized the country's capital Sanaa before going on to take over Yemen's southern regions and capture Aden.
At least 6,000 people have been killed in the ongoing civil war in Yemen, nearly half of them civilians, and more than 27,000 injured since March, according to the United Nations.
