On TheGameMechanic's stream, he could attack an Inca city through a tunnel with a melee unit without having it be "next" to the city.
Long story short.... DO NOT place tunnels next to city centers or encampments. Enemy melee units can attack through without getting close.
EDIT: "B0RDERL1NE (Carl from Firaxis): Inca Qhapaq Nans function a bit like siege worms. Road opens up, attack immediately comes through!" -from twitch chat
"B0RDERL1NE: Tunnels do not help sieging at all, but yes you are able to attack through them." - twitch chat
Me: "@B0RDERL1NE Could a melee ship attack a city through a tunnel adjacent to water?"
"B0RDERL1NE: @ME Tunnels are solely on land, ships cannot go on land."
It was worth asking.
Can a ranged unit shoot through the tunnel? If so, and if they have a range of two or more do they still need to be next to the tunnel in order to attack through it? Can units be attacked through tunnels?
