Italian police say they are searching for the sender of pig heads to Rome's main synagogue, the Israeli Embassy and a city museum hosting an exhibit on the Holocaust.

Police headquarters said Saturday the anti-terrorism squad was handling the case. The pig heads arrived in three separate boxes, all sent by a delivery service unaware of the contents.

The deliveries were made Friday, three days before an international memorial day for Holocaust victims.

In a tweet, Rome Mayor Ignazio Marino condemned what he called intimidation of the city's Jewish community.

Local media reported Saturday that anti-Semitic graffiti also appeared outside a municipal building in a Rome neighborhood.
