getting the ID of newly added recorded using linq to entities

Hi this is my first project using linq to entities. I've figured out how to create a new record I just need to get the ID that was assigned to it so I can use it as a FK in an extension table when I add the entries there. I'm allowing users to create request, the request can be for multiple pieces of equipment so I have a Request and RequestedEquipment table. Here is the code I'm using to create the request:

public void addReq(ReqType reqType, Employee reqBy, Location loc, string comm)
        {
            int reqID;
            Request req = new Request();
            req.Comments = comm;
            req.Employee = reqBy;
            req.ReqType = reqType;
                req.RequestStatus = findReqStat(1);
            req.Location = loc;
            entities.AddToRequests(req);
            entities.SaveChanges();
        }

How can I get the ID of the request that was created so I can use it to Create the needed entries in the RequestedEquipment Table?
