This BBC report http://www.bbc.co.uk/news/world-middle-east-43014081 ends with this:
'Iran - together with Russia - is a key supporter of Syrian President Bashar al-Assad, whose troops have been fighting rebel groups since 2011.
Last November, a Western intelligence source told the BBC that Tehran was establishing a permanent military base inside Syria.Israeli Prime Minister Benjamin Netanyahu has warned that "Israel will not let that happen".
Iran has faced accusations that it is seeking to establish not just an arc of influence but a logistical land supply line from Iran through to the Shia Hezbollah movement in Lebanon.'
Hezbollah? Has anybody asked Jeremy Corbyn what he thinks of his friends in Hezbollah receiving money and weapons from his former paymasters in Iran?
