I wouldn't say that it breaks UDP connections since UDP doesn't really rely on an actual connection. It causes a data loss which should be expected when using UDP.
TCP will most likely handle the problem by resending the lost package many times until any matching ackknowledge arrives or the connection will time out. So a BGP attack can break a TCP connection and potentially deny following connections. But it requires more than causing one package being misrouted to disrupt a live TCP connection. That's probably what other people referred to.
