The attack at Manchester's Heaton Park synagogue happened on Yom Kippur, the holiest day in the Jewish calendar - and just five days before October 7.
Known as the Day of Atonement, Yom Kippur is a solemn day of fasting, prayer, and reflection for Jews around the world.
This year, it started on Wednesday evening and ends at sundown on Thursday.
Heaton Park was packed with worshippers taking part in a series of long and solemn services.
To add to the significance, Tuesday will mark the second anniversary of attacks on Israel by Hamas terrorists, in which 1,195 people were killed and 250 taken hostage.
