Armed men stand guard outside a local authority compound after taking it over in Yemen’s southern port city of Aden February 16, 2015. Forces loyal to Yemen’s president said they had seized strategic buildings in the southern city of Aden on Monday after a five-hour battle, escalating a civil conflict threatening to split the country in two. The militias supporting Abd-Rabbu Mansour Hadi wrested parts of Yemen’s economic hub from security forces allied to the Houthi movement, including its main power station and intelligence headquarters, sources said.
