Nigeria has intercepted several containers from an Iranian ship containing rocket launchers, grenades, and other explosives. The containers were disguised as building materials, and apparently bound for Gaza.
Of course, building materials are one of the things that Palestinian civilians desperately need to rebuild. And equally "of course", Iran is well aware that anything Palestinians need is something that can by cynically used as camouflage in order to further their real goal of killing more Israelis. I'm sure the Palestinian people are thrilled that building materials undoubtedly will be even less likely to be admitted into the strip now than before this little incident.
