Syria is far easier. It can be reached by a fairly cheap flight to Turkey, and a handler can escort you over the border. But, as police are now pointing out, after that you have no control. Those genuinely seeking to do humanitarian work are at the mercy of whoever provides the transport. Even those seeking to fight Bashar al-Assad’s forces can end up being sucked into one of the many rebel vs rebel battles. There are Jabhat al-Nusra, the Islamic State of Iraq and al-Sham, the Islamic Front – groups who fight each other as well as Assad. With no clear battle lines, no one who travels there can be sure whose side they’ll end up on.
