So says the Arabic language Beirut Observer who got it from western intelligence officials.

Haaretz:

Hezbollah is planning an attack on Western targets, a Lebanese news website reported on Tuesday, basing its claims on information intercepted by a Western intelligence agency.

According to the Beirut Observer article published Tuesday, Western intelligence officials believe Hezbollah intends to strike Western targets, citing the unusual movement of suspected Hezbollah and Iranian Revolutionary Guards operatives.

The report said the intention of such an attack is to divert global public opinion from the indictments expected to be issued by a special United Nations tribunal dealing with the assassination of former Lebanese PM Rafik Hariri.

Lebanese officials and Western diplomats expect the court to accuse Hezbollah members of involvement in the assassination, a prospect Lebanese politicians fear could fuel further tensions.

The Lebanon tribunal, the world's first international court with jurisdiction over the crime of terrorism, was set up to try those accused over the 2005 bombing that killed Lebanese ex-prime minister Hariri and 22 others.

Hezb'allah is panicking. Since their recent takeover of the Lebanese government, things have not been going very well, They have yet to be able to form a cabinet with their puppet prime minister proving to be unpersuasive. The sealed tribunal indictments - once opened - might precipitate a civil war between Sunni and Shia because the murdered Hariri was particularly beloved among Lebanese Sunnis.

If they feel they have to hit Israelis or other westerners in order to distract the Lebanese population from their traitorous alliance with Bashar Assad of Syria (who probably ordered the hit on Hariri but won't suffer the consequences due to UN cowardice), they are truly worried that they may be forced to rule Lebanon at gunpoint.

Any conflict would be pretty one sided. The Sunnis are very far removed from the civil war when their militias were formidable fighting forces. But it wouldn't take long before they could be reconstituted and give the Hez all they could handle.
