This BBC report http://www.bbc.com/news/world-middle-east-43455970 is pretty vanilla, albeit there was more distaste when they reported upon Priti Patel talking to the Israeli regime than over gun smuggling to Israel's enemy.
However this at the end of the report struck me:
'Israel has long tried to prevent arms reaching Palestinian militants.
Israel and Egypt maintain a blockade around the Gaza Strip to prevent weapons smuggling and attacks by Gaza-based militants. There are also tight security measures to stop arms getting into the hands of militant cells in the West Bank.'
