Airstrikes by a Saudi-led coalition targeted Yemen's capital today, hitting at least three houses in Sanaa and killing at least 14 civilians, including women and children. <br/><br/>The attack was the latest by the coalition, which has been waging a relentless air campaign against Yemen's Iran-backed Shiite rebels for the past two years in an effort to bring the internationally recognised government back to power. <br/><br/>Recently, the strikes in and around the capital, Sanaa, targeting army compounds and other locations of the rebels known as Houthis, have intensified. <br/><br/>Today's strikes hit the city's southern neighbourhood of Fag Attan. The death toll was expected to rise further as rescuers pulled more victims from under the rubble.<br/><br/>The escalation comes amid signs of fracturing between the two main components of the rebel alliance in Sanaa, the Houthis and loyalists of ousted President Ali Abdullah Saleh, a standoff that has triggered fears of street violence.
