JERUSALEM (JTA) — Two Jewish teens were arrested for vandalizing a synagogue in the central Israeli city of Raanana.

The 17-year-olds were arrested on Tuesday for the weekend vandalism. They told police that they acted out of boredom, the Times of Israel reported.

The teens allegedly tore mezuzahs off the doorways of the Ahavat Reim Synagogue, and painted crosses and swastikas on the parchments — reportedly in their own blood — before sticking them on the walls of the synagogue.

About a dozen mezuzahs also were torn from the doorposts of nearby apartments, and local residents said they saw the teens in the area.

Raanana is home to a large number of immigrants from the United States and other English-speaking countries, as well as from France.
