Occupied Jerusalem: Israel's government is warning its citizens to beware of possible attacks when they travel abroad, singling out threats by the Lebanese group Hezbollah.

A year ago, a prominent Hezbollah commander, Emad Mughniyah, was killed in an explosion in Syria. Hezbollah blamed Israel and pledged revenge.

Israel and Hezbollah fought a fierce monthlong war in 2006.

In the advisory issued Sunday, the government tells Israelis to take precautions when they are abroad. These include avoiding most Islamic countries, rejecting tempting offers and unexpected gifts, turning down invitations to unexpected meetings and avoiding routines.

The government issued the advisory with the approach of the Passover holiday, a heavy travel period.
