Warning siren in the middle of Shemoneh Esrei

Q: What should a person do if he hears a warning siren for an incoming missile and he is in the middle of the Shemoneh Esrei?
A: He should certainly run to the bomb shelter and continue to daven the Shemoneh Esrei there. This is based on two reasons: 1. It is a case of a life-threatening situation. 2. Walking in the middle of the Shemoneh Esrei without speaking is not considered an interruption. For example, if I am davening the Shemoneh Esrei and a child is bothering me something terrible and I cannot concentrate, I can move to another place. Or if I am davening by heart and I cannot remember "Ya'ale Ve-Yavo," I can go and get a siddur. Speaking is forbidden but there is no problem of moving if there is a need. Therefore, if I am in the middle of the Shemoneh Esrei and I hear a warning siren for an incoming missile, I should go to the bomb shelter without talking and continue to daven in the place where I left off (see Piskei Teshuvot, Orach Chaim 104 and Shut Be'er Moshe 3:13).
