Lebanon just caught Hezbollah moving assassination-grade explosives toward Beirut

Lebanon just stopped a car full of explosives heading into Beirut.

And both men inside it are suspected Hezbollah members.

This happened about a week ago at the Dahr al-Baidar checkpoint. That's the mountain road connecting the Bekaa Valley to the capital. Security forces caught the two men in the afternoon, driving straight towards Beirut.

One of them is the son of a Hezbollah official. The other is a member of the group too.

So how much explosive material are we talking about? Depends who you ask.

A judicial source told AFP it was half a tonne. 250 kilograms of TNT-type explosive, 250 kilograms of C4.

Judicial officials told the Associated Press the real number was 780 kilograms. Still 250 kilograms of TNT and 250 of C4, which leaves 280 kilograms nobody has explained.

And Lebanon's MTV reported a third version. 780 kilograms again, but this time 216 kilograms of C4 and 281 kilograms of Tetryl, plus nails and small containers packed in with it.

Three accounts. Nobody official has picked one.

What the men actually told investigators depends on the source too.

The Associated Press says they were told to move the material from Baalbek to Beirut, no explanation given, and to hand it to a man south of the city known by the nom de guerre Zulfiqar.

MTV has a similar story, but with different names. A contact called Sajed told them to deliver the explosives to Beirut's southern suburbs, for a man named Dhulfiqar.

AFP's judicial source says something else entirely. The real destination is unknown, and Lebanese authorities haven't confirmed that account at all.

Nawaf Salam, Lebanon's Prime Minister, says quote "our government will not tolerate anyone who dares to tamper with the country's security".

He's promised a full investigation. And he says the government will come down hard on anyone holding, moving or using weapons outside state control.

Salam says he understands why this has frightened people. C4 has been used in some of Lebanon's most notorious political assassinations.

Paul Morcos, Lebanon's Information Minister, says the two men have been handed to judicial authorities. Security agencies are now chasing whoever else was involved.

Adel Nassar, Lebanon's Justice Minister, posted online that the investigation into the seized explosives, and everything that follows from it, will continue to the very end.
