Saudi Arabia and the UAE urged Yemenis to observe a cease-fire in Aden and resolve their differences through dialogue.
The separatists, who want an independent south Yemen, had agreed to support the government of President Abed Rabbo Mansour Hadi to defeat the Houthis from the north who sparked the conflict in 2014 when they seized Sanaa.
But tensions between the separatists and Hadi’s forces have spilled over on a number of occasions in Aden.
Griffiths said he was alarmed by the violence in Aden and Abyan. "I condemn the unacceptable efforts by the Southern Transitional Council to take control of state institutions," he added.
He said the incidents in Aden raise unanswered questions about Yemen's future and the port city must be under the exclusive control of Yemeni state institutions.
Griffiths also told the Security Council via a video link that he "condemned the ongoing Houthi attacks on civilian facilities in Saudi Arabia."
In recent days, the Iran-backed militia launched 10 drones towards a Saudi Aramco gas plant, which was condemned by the international community and the Arab coalition said that the Houthis are threatening global energy supplies.
Griffiths said: "the division of Yemen has become a real threat and we must redouble our efforts. Yemen must return to normal to prevent the disruption of the social fabric."
He also said that there have been discussions about the exchange of Yemeni prisoners, but negotiations are slow and prolong their suffering.
Meanwhile, UN Assistant Secretary-General for Humanitarian Affairs and Deputy Emergency Relief Coordinator Ursula Mueller said infrastructure and water networks were heavily damaged in the Aden clashes.
She said the World Food Programme and the Houthis signed an agreement to protect food aid but humanitarian agencies are suffering enormous restrictions in the north imposed by the militants.
"More than 100 humanitarian projects await Houthi approval and the UN faces difficulties in northern Yemen due to restrictions and harassment," she added.
"Yemen remains the biggest challenge for humanitarian agencies," Mueller told the Security Council.
