The sources didn’t specify what weapons were seized in the March raid, though said in recent months security services have thwarted numerous attempts by Iran and its allied groups to smuggle in arms including Claymore mines, C4 and Semtex explosives, Kalashnikov rifles and 107mm Katyusha rockets.

Most of the clandestine flow of arms into the country has been bound for the neighbouring Israeli-occupied West Bank Palestinian territory, according to the Jordanian sources. However, some of the weapons – including those seized in March – were intended for use in Jordan by the Brotherhood cell allied to Hamas militants, they said.
