A tribesman carries his firearm as he attends a tribal mediation to resolve a deadly feud that has erupted between two local tribes in the Khawlan area, about 40 km (25 miles) east of the Yemeni capital Sanaa February 16, 2013. Tribal arbitration and mediation provides an effective and widely-used means of conflict resolution in Yemen, which has an ingrained gun culture, and has the second highest rate of private gun ownership in 178 countries, according to a Small Arms Survey report published in 2007. As well as wearing curved daggers at their waist, it is not unusual for Yemeni men to carry AK-47 assault rifles, hunting rifles and pistols. Picture taken February 16, 2013.
