The NYPD has increased security in Jewish neighborhoods following the deaths of seven Israeli tourists in a bus bombing in Bulgaria, said officials.
"The NYPD has redeployed its critical response vehicles which, comprise part of the department's daily counter terrorism posture, to focus on Jewish neighborhoods and institutions as a precaution in the wake of the attack in Bulgaria<" said Dept. Cmsr. Paul Browne.
As many as 100 critical response vehicles and two officers at each post will keep an eye on Jewish neighborhoods and Jewish institutions across the five boroughs.
The daytime bombing killed seven people and injured dozens on a bus full of Israeli tourists on Wednesday.
Bulgarian officials believe it was most likely a suicide attack.
Israel stood by its claim Thursday that Iranian-backed Hezbollah was responsible and vowed to hit back.
