FEARS that the Middle East could explode into all-out war are ratcheting up today after Iran vowed vengeance for a deadly Israeli missile strike on its embassy in Damascus, the capital of Syria.
At least 11 people were killed when a consular annex was reduced to rubble by strikes which Iran says were carried out by Israeli F-35 fighter jets.
Also among the dead is a representative of the Hezbollah terrorist group Hussein Yusuf.
Both Iran and Hezbollah have vowed vengeance, with Iran's president Ebrahim Raisi saying this strike will not go unanswered.
The suggestion is that perhaps Israel has crossed a threshold with a strike on an embassy.

Embassies are sovereign soil of the nations they belong to, so this was a strike on sovereign Iranian soil in Syria and in one sense it is an escalation and the concerns that this could spiral out are in many ways well founded.
Interestingly today we've heard reports in the local media in Syria and in the region that America appears to be distancing itself from this strike, officials saying they had no advanced knowledge.
It would appear that the reason for this missile strike was the meeting between these Revolutionary Guard commanders and the representatives of Hezbollah.
We will now have to wait and see how Iran chooses to take its revenge.
Now of course, if you are an Israeli diplomat living abroad, then you may well think that you are now more of a target.
Because Israel has targeted an Iranian embassy, we may expect to see the possibility that Iran may target Israeli diplomats or missions around the world.
And we have just seen in the last few days suspected Iranian agents attacking an Iranian journalist here in London.
Tehran is showing, perhaps by this stabbing, that it maintains the ability and the capability to attack people it sees as enemies of the regime around the world.
Some context that we understand that Tehran employs criminal proxies to carry out that sort of dirty work doesn't necessarily have the same sort of sophisticated overseas operations that we might expect of other hostile actors like Russia.
But nonetheless, I think in the wake of what happened in Damascus on Monday, combined with what's been happening across the region in recent months, there is concern and anxiety to see how Iran responds and what that will elicit from Israel.
