Yemeni Houthi fighters and army allies advanced in a column of tanks into central Aden, the main foothold of loyalists of President Abd-Rabbu Mansour Hadi, witnesses said. The advance into the Khor Maksar district came despite a week of Saudi-led air strikes against the Houthis aimed at reversing their gains on the battlefield. http://english.ahram.org.eg/News/126672.aspx
