In this picture taken on Sunday, April 26, 2015, a man tends to a vehicle as Jordanian trailer trucks sit idle at Jaber border crossing between Jordan and Syria north of Mafraq, Jordan. Jordan’s overland trade has largely been paralyzed by recent border attacks from insurgents in neighboring Syria and Iraq – a spillover of regional turmoil threatening a close Western ally that has thus far succeeded in fending off Islamic militants.
