Were UK and Ukrainian special forces trying to blow up the bridge at Kerch?

When I first heard about the events at the entrance to the Sea of Azov 2 days ago I immediately thought of this article below from May this year, although I could not remember the details:

Ukraine should blow up Putin's Crimea bridge
Ukraine should now destroy elements of the bridge.

While that course of action would be an escalation against Putin and one that would almost certainly spark Russian retaliation, this bridge is an outrageous affront to Ukraine's very credibility as a nation. Of course, from Putin's perspective that's the whole point. The bridge cost Russia's near-bankrupt government billions of dollars, but it offers Putin a formal physical and psychological appropriation of Ukrainian territory.

Fortunately Ukraine has the means to launch air strikes against the bridge in a manner that would render it at least temporarily unusable. Because of its significant length, the Ukrainian air force could strike the bridge while mitigating the risk of casualties by those traversing it.

It is not at all difficult to believe the following story although at this stage it is mostly speculation for which there is no direct evidence.

I suspect that further evidence for this will come out in the next few days although it is possible that the Russian authorities may decide not to reveal the details of this heinous act  as it would provide "irrefutable proof of an ATTEMPTED, unprovoked, sneak-attack-nuclear-strike upon Russia Territory" 

Countries have gone to war for far less than this. 

Report that British and Ukrainian special forces were intercepted by Russian intelligence trying to blow up the Kerch Bridge

Hal Turner is saying that:

COVERT INTEL is buzzing with word that a NATO Special Atomic Demolition Munition (SADM), a Diver deployable device, was being transported by Ukrainian and British Special Forces to the Kerch Strait to be used against the Crimean bridge. 

Find information on the Special Atomic Demolition Munitions (SADM) HERE

He is reporting that the Russian intelligence authorities became aware of the plans and they were tracking the device was  loaded onto a Ukrainian Tug (escorted by 5 warships!! - 3 in the Black Sea, including one NATO vessel, and 2 waiting in the Sea of Azov).

According to this version of events ground attack jets and Helicopter gunships, plus a warship armed with Anti-Submarine Missiles and Torpedoes were waiting for the Ukrainians.

This is the first time that force has been used by the Russians since the events in Crimea in 2014, and they  have never blockaded the Sea of Azov.

It would have to be asked why the Russians would use such a degree of force
"just for a tug and a few old Ukrainian ships."

Russia is used to frequent provocations from the Ukrainians (to little effect)  but this time Russia decided to ACT.

Hal Turner says that:

An SADM explosion would have brought down the bridge and melted the foundations, but would have looked like a conventional IED blast from above, due to the underwater detonation and relatively low yield of less than 1KT.

This was a WW3 level provocation STOPPED by the Russian FSB and Special Forces!

 He is saying that the device may have come from the UK.

We have seeing incredibly aggressive and febrile rhetoric from Britain (second-to-none)

Device thrown overboard?

Further, Turner reports that he has indications ("intell") that the Ukrainians panicked when they realized the Russian vessels were coming to intercept them, and they THREW THE DEVICE OVERBOARD!   

The area is now full of vessels and scuba divers trying to find "a functional - albeit low yield - nuclear bomb" might be.

Just imagine for a minute if the Russians find what they are looking for.

The stakes on this are very high.  If such a device is found, that would be irrefutable proof of an ATTEMPTED, unprovoked, sneak-attack-nuclear-strike upon Russia Territory.

Why Poroshenko called for immediate martial law

According to Turner's reporting "intell" are saying and it makes some sense to speculate that all this is the reason Ukraine pancked and enacted immediate Martial law, calleling up Reserve troops, and is deploying those reserves to areas bordering Russia.  

They fear a land invasion as retaliation for what took place

Russia has undertaken increasied security measures: Zakharova

Official spokeswoman for the Russian Foreign Ministry, Maria Zakharova, commenting on the incident with the Ukrainian ships in the Kerch Strait, said that Moscow had taken increased security measures in connection with threats to destroy the Crimean Bridge.

“The Russian side has taken increased security measures, and especially given the calls for the destruction, undermining, and so on of the Kerch bridge,” she said.

The diplomat also did not rule out new provocations by the Ukrainian authorities. According to her, Kiev is not able to control not only what is happening in foreign territorial waters, but also not able to dominate the territory of Ukraine.

Also, the representative of the Foreign Ministry, speaking on the TV channel "Russia 1", said that Moscow regrets the refusal of the UN Security Council to hold an urgent meeting on the situation in the Kerch Strait.
