MONTREAL - Montreal's Jewish community fears it is being targeted in an orchestrated campaign of hatred.

B'nai Brith's local chapter issued a press release Monday following weekend attacks against five institutions.

Three synagogues, a Jewish school and a daycare had their windows smashed with rocks.

"Following what appears to be an orchestrated campaign of anti-Semitic attacks, there is particular concern about the targeting of a school and daycare," the group said.

Police suspect the attacks are related. They have no eyewitnesses but are hoping surveillance video might offer some clues.

No arrests have been made.

B'nai Brith says it's now time to review any past vandalism at Jewish institutions that may have been written off as isolated incidents; the organization says it looks like the community is being targeted.

The group said this weekend's attacks brought back "painful memories" of the firebombing of the city's United Talmud Torah School.

The school was torched just before Passover in 2004.

Local men Sleiman El-Merhebi and Simon Zogheib were charged in the case, which made international headlines and drew donations to help rebuild the school's library.
