Roads across Israel were gridlocked on Thursday as Israeli security forces launched a nationwide drill at the height of the afternoon rush hour.

The comprehensive exercise included all arms of the security establishment: Israel Police, the Israel Defense Forces, firefighters and Magen David Adom emergency service.

A police statement issued Thursday said to expect major traffic delays and road closures and asked the public to be patient.

During the drill, security services dealt with simulated emergency scenarios, including simultaneous terror attacks at multiple locations.

Israel Radio reported heavy traffic along the coastal road, near Caesarea, Olga and Tel Aviv in central Israel.

There were also reports of serious delays along Ayalon Highway as well as major roads in the Jerusalem area.
