Police recorded 50 homicides between January and May 2011, compared to 37 murders thus far in 2012.

But the number of knife possession incidents has risen in several police districts.

In the Tel Aviv police district, for example, there was a 50 percent increase in knife possession cases opened in 2011.

Police said the rise was due to an increase of body searches.

Figures for 2012 were not immediately available.

Law enforcement and government remain concerned about the affect of alcohol on youths, and have already banned drinking in public, as well as the selling of alcoholic beverages after 11 p.m.

But the measures appear to have done little to stop teenage binge drinking.

In 2011, 7% of all criminal offenses were carried out by youths, representing a 12% drop compared to 2010.
