ABUJA. Nigerian authorities have arrested three Lebanese men in northern Nigeria on suspicion of being members of the Lebanese movement Hezbollah. Soldiers uncovered a hidden arms cache that authorities believe belonged to members of the Shia political party and armed group, the military and secret police said on Thursday.The three suspects were arrested between May 16 and May 28 in the north’ biggest city Kano, said Captain Ikedichi Iweha, the city’s military spokesman in a written statement.All suspects reportedly admitted to being members of Hezbollah under questioning.A raid on the home of one of the Lebanese had uncovered 60mm anti-tank weapons, four anti-tank landmines, two rounds of ammunition for a 122mm artillery gun, 21 rocket-propelled grenades, seventeen AK-47s with more than 11,000 bullets and some dynamite, Iweha said."The arms and ammunition were targeted at facilities of Israel and Western interest in Nigeria,” Iweha said, but did not elaborate.Separately, five fighters from Chad and two from Niger were arrested among fighters fleeing a two-week-old offensive against the Boko Haram armed group in the north-east, as they tried to cross the border into Chad, Nigeria’s defence spokesman Brigadier General Chris Olukolade said in a written statement.
