gives graph g minus e. If g is undirected, then e is treated as an undirected edge; otherwise it is treated as a directed edge. If there are multiple edges between the specified vertices, only one edge is deleted.

DeleteEdge[g, e, All]
will delete all edges between the specified pair of vertices. Using the tag Directed as a third argument in is now obsolete.
