I had handled such situation in my office once.
I would suggest to talk to both of them one by one and try to know reasons behind their behavior. After that you talk to both of them jointly and warn them that such incidence will not be tolerated again simultaneously in consultation with your seniors issue them waning letter or show cause notice to restrict such incidence in future.
Terminating them is not a solution. They should be given one chance and others should also get a lesson from them that such things will not be tolerated in the office.
