Well, it seems there are two sides to every story. I'm favouring the one in this post as I've seem the inaction of fighting in the north by Hadi's forces there. Their is an strange politic happening that has the houthi as a bit-player used to cut down or weaken your opposition - STC in Yemen's case as they want to separate from the north.

The strategic expert from Paris, Gamal Badr al-Awadhi, said that UN envoy Martin Griffith is seeking special gains by colluding with the Houthi rebels side and his flagrant violations of UN and Security Council resolutions, noting that Griffith condones the comic representation of the so-called delivering the see port of Hodeidah by the Houthis, The coastal areas were represented by handing over the
Huthis to other Huthis in civilian clothes.

Al awadhi added that the suspicious silence of Yemeni President Abed Rabbo Mansour Hadi and the rest of the frozen fronts or the so-called national army in Marib refers to an unspoken complicity to push the Houthi militias towards Daleh , which is the only front burning in Yemen where it is clear that the operation aims to weaken the southern forces, In front of the coup militias which defeated and progress from one front to another with support from the Arab alliance aircraft.

"There are extremist parties within the Islah Party (the Muslim Brotherhood in Yemen) seeking to return to the south once again to carry out terrorist acts and turn the south into another Afghanistan, an Roceya Al-baity an Yemeni human right activist said from Paris.

This is not the first time that extremist groups have tried to storm and control the city of Aden, Mukalla at the beginning of the war in 2015, but the southern resistant faced terrorism and assassinations and kicked the terrorists out of most of the southern provinces.
For his part, human rights activist Shadi Alwan from Sweden pointed out that the battle of Daleh represents a turning point to strengthen the military role of the southern forces, which affirmed in more than a battle of their ability to progress on different fronts and liberation in the West Coast and the Mokha Seaboard and Bab al-Mandeb.
