Nice.

That last part of the video doesn't make much sense. We KNOW that the guidance section is before the warhead. The animation is probably not from the MOD. I think that even if the warhead separates, it would have to include that guidance section, for obvious reasons. We haven't actually heard any official government/military sources saying the warhead separates, only these journalists (and you know how bad Iranian journalism is).
Ballistic missiles, by definition, do not (cannot) do evasive manoeuvres. A ballistic missile is guided during relatively brief periods of flight only. Multiple Reentry Vehicle (MRV) simply means more than a single warhead. A multiple reentry vehicle payload for a ballistic missile deploys multiple warheads in a pattern against a single target. Multiple independently targetable reentry vehicle (MIRV) means containing several warheads, each capable of being aimed to hit one of a group of targets (i.e. different targets). The maneuverable reentry vehicle (abbreviated MARV or MaRV) is a type of ballistic missile whose warhead is capable of shifting targets in flight. It often requires some terminal active homing guidance to make sure the missile does not miss the target, because of the frequent trajectory shifts. It doesn't mean 'capable of evasive manoeuvring': although one could use it to evade interception, this would mean going to a different target alltogether (rather than e.g. dodging and weaving towards a given target).But add to that the fact they are firing in bundles, have cluster/bomb-let warheads and certainly use evasive manoeuvring, I doubt any missile defence in these nations would stand a chance even without a saturation attack from Iran.

I'm just saying: don't hold your breath, this might be journalistic bullshit.
@VEVAK I disagree. Look at this still image of the Khalije Fars, which is derived from the Fateh-110, you can clearly see the entire missile.
And look at these images of the Fateh-110 guidance sections:
Consider that the Fateh would need a large guidance unit for to get such excellent accuracy. Now consider that this is a tactical missile, meant to be cheap to produce. Seems to me that an extra guidance section would take up too much room, where results can be gained simply by reducing the size of the warhead slightly, using lighter materials (carbon fibre) and better propellant.
I still see no proof of a rocket motor. All I see are red protective coverings.
Thats true,but its very obvious that the guidance section has had a major redesign with the fins being moved to the rear and the front of the section tapered and they wouldnt have done this without a very good reason.A separate guided warhead makes very good sense,not only can it glide further it can also perform better evasive maneuvers and its a much smaller target to detect and to try and intercept.One wonders if we`ll see this upgrade done on the antiship variant the khalij farsI still see no proof of a rocket motor. All I see are red protective coverings.
The separation warhead is another improvement of the Fateh series as the internal volume has increased, the guidance section is now packed in front of the control surfaces. Now the fins are positioned at the aft, which is a good configuration for the maneuverable re-entry vehicle. The RV can now glide for a longer range as aerodynamic drag is reduced as well as lower radar signature. As no retro boosters are installed, the separation should take place late probably with a simpler spring system. It lacks a gas driven nozzle steering system as on the Iskander which reduces its effectiveness against exo-atmospheric interceptors such as the THAAD but remains effective against endo-atmospheric systems like the PAC-3.
Guidance system is accurate gimballed INS most likely coupled to GPS/GLONASS and as they stress navigational redundancy a stellar navigation system would also be a additional candidate.
Expect something like the Zolfaghar-313 with use of composite materials as the Fateh-313, likely enabling a range of 1000km. Together with the twin launcher of the Fateh and the comparative mild and dry climate of Iran which doesn't make a canister launched system necessary, the system is a very efficient system for the use against high value targets.
@VEVAK
A PBV/a RV with an booster would make this conventional tactical missile more expensive. Its only real benefit would be exo-atmospheric manouvering to evade systems like THAAD or bring down their range and PK. The Iskander which is in a similar role has a elegant solution to pack this capability into the already existing first stage TVC system via cold gas or hydrazine steering nozzles. This solution brings down the cost. The Zolfaghar has no such already existing subsystem as it has no TVC, which is again economical compared to the Iskander. The Fateh/Zolfaghar launcher just has to position it quite accurately because in the first phase these missiles act like unguided heavy rockets.
So the Zolfghar and Fateh are elegant cost-effective designs. Adding a gas nozzle steering system to the PBV would only bring a benefit against exo-atmospheric interceptors for a much higher cost. Which countries field systems like THAAD in useful numbers? That red cap at the end of the RV should be related to the spring system which unlike the retro rocket system on the Sedjil is again a cost effective solution.
For range the initial impulse of the first stage main engine is enough for a 700km missile, a low power "sustainer" at the PBV is not of much benefit.
I agree with you that a variant with optical/passive radar of the Zolfaghar are also likely, this adds additional guidance redundancy.

Iran claims Zolfaghar missile has 700 km range
Jeremy Binnie, London - IHS Jane's Defence Weekly
28 September 2016
The Iranian Ministry of Defence (MoD) released this photograph of a missile labelled as a Zolfaghar being launched, but this missile is different from the Zolfaghars displayed during the 25 September ceremony. The MoD also released video footage showing what was said to be a Zolfaghar being launched and hitting a target, but it could not be determined whether the missile was the same as the ones seen in the ceremony.

Iranian defence minister Hossein Dehghan claimed that the new Zolfaghar (Zulfiqar) ballistic missile has a range of 700 km during a 25 September ceremony that inaugurated the weapon's production line.
Unveiled for the first time during a military parade four days earlier, the Zolfaghar is a new version of the Fateh-110 family of solid-fuel tactical ballistic missiles that reportedly uses a submunitions warhead.
The missile that was labelled as a Zolfaghar in the parade appeared to be different from the ones that were displayed during the 25 September ceremony.
The Ministry of Defence also released video footage purportedly showing a Zolfaghar being launched and hitting a small target. The projectile appeared to approach the target at a low trajectory for a ballistic missile and destroy it using a small unitary warhead.
Dehghan told parliament on the same day that production of Sejil, Ghadir, and Khorramshahr missiles would begin before the end of the Persian year in March 2017.
The Sejil is a solid-fuel medium-range ballistic missile that the Iranians said would go into production after the second test was announced in 2009, although the type has rarely been seen since then. Iran announced in March 2015 that the Ghadir long-range anti-ship missile had entered mass production. Iranian officials do not appear to have previously referred to the Khorramshahr missile.
