Hanoi, Jumada II 28, 1436, Apr 17, 2015, SPA -- Vietnamese authorities were searching Friday for two pilots a day after their Sukhoi Su-22 fighter jets lost contact and traces of jet fuel were spotted off the southern coast. The two Russian-made fighters jets were on a training exercise when they disappeared around noon Thursday, AP quoted the Ministry of Defense as saying. A search aircraft spotted four floating jet fuel barrels and traces of fuel in the sea, the statement said. Two of the barrels were recovered. The navy, maritime police and the coast guard were taking part in the search in the south-central province of Binh Thuan, about 1,600 kilometers (995 miles) south of Hanoi, said disaster official Pham Hung Tan. --SPA 10:59 LOCAL TIME 07:59 GMT www.spa.gov.sa/w
