Avinu Malkenu on Shabbat
Question
I went to a different synagogue this Shabbat than I usually do. At this synagogue they recited Avinu Malkenu on Shabbat. They announced they were doing it because of the hostages in Gaza. What makes the recitation of Avinu Malkenu permitted on Shabbat? Under normal circumstances, Avinu Malkenu is never recited on Shabbat except for Yom Kippur Neilah.
