Make what you want of it but remember that the US are supporting, funding and arming Al Qaeda linked rebels in Syria, they did the same in Libya and best of all they created Al Qaeda in the first place.
Don't believe me? Hilary Clinton admits it http://youtu.be/Dqn0bm4E9yw (albeit amongst half truths and lies).
20 embassies closed across the middle east, well that's a bit vague isn't it? Surely if this terror surveillance is so good then you'll know exactly where and what they're going to do, get there first and prevent it without the need to scaremonger everyone, tell us not to travel because of a non-specific threat to our safety and pointlessly inform everyone all these embassies are closed as a speculative precaution. It is complete nonsense.
Al-Qaeda is a longstanding US asset used strategically as enemy or ally. Terror threats are fabricated. Bin Laden was used as the West's prime enemy years after he died. Obama didn't order his killing, he was seriously ill with kidney disease among other illnesses. In December 2001 he died naturally- The Pakistan Observer reported it, so did BBC and Fox News. In July 2002, The New York Times said he's been dead for "almost six months." He was "buried in the mountains of southeast Afghanistan.". Al Qaeda or Bin Laden is just a name that's been thrown about to justify a certain action.
What's Benghazi got to do with it? Well President Nixon was impeached not just because of what happened but because of his cover up of Watergate so Obama really needs a media distraction every time the heat gets turned up on what happened at Benghazi and why it was covered up.
The US and UK embassy are closed in Yemen and all US and UK citizens urged to leave the country immediately. "The security threat level in Yemen is extremely high" we are told hours after one of the many regular drone strikes killed four suspected al-Qaeda militants in the country. Note that these drone strikes always target suspects and kill more innocent civilians than they do suspects. Normally this is kept rather quiet but this strike is widely reported as if to say "hey we killed some terrorists, we've got this terror alert under control, we're keeping you safe!"
As well as the false flag media distraction it's another dollop of Islamaphobia and another chess piece moved in the game to control the Middle East, what's the next move? More bullshit coming soon no doubt, lets hope less and less people carry on believing it.
