Forces loyal to Yemens former President Abd Rabbuh Mansur Hadi have been arresting and evicting hundreds of civilians from the southern port city of Aden to the north, local officials say.
They said secessionistswere raidingshops, restaurants and homes, detainingmore than 2,000 people whom they said posed a security threat.
Aden fell to pro-Hadi forces who werebacked by Saudi air cover after fierce fighting with Houthi fighters in July 2015.
Also Sunday, theHouthi movement accused Saudi Arabia of launching airstrikes that killed sevenpeople, shaking a truce that has largely held throughmore than two weeks of UN-backed peace talks.
"The aggressor's planes bombed various districts in the Nehmdistrict, leading to the death of seven martyrs and woundingthree," the Houthis said in a statement.
On Saturday, Hadi's representativespulled out of direct peace negotiations held in Kuwaitwith Houthis after "substantive issues" were discussed in three joint working groups formed under UN auspices.
The UN special envoy to Yemen Ismail Ould Cheikh Ahmedheld then separate talks with the warring parties in a bid to break theimpasse.
Each side accuses the other of not respecting the truce which has been constantly broken since it came into force on April 11.
In a statement on the sabanews website, a Houthi delegate said the three joint teams will resume work "after an agreement on the form of the state and the transitional authority."
Without such an agreement, the talks were "a waste of time" said the delegate, adding that Hadi's side was "an adversary and it is unacceptable that he embodies the state."
The Houthisand their allies have demanded the formation of a consensus transitional government before forging ahead with other issues.
They have also demanded the withdrawal of a US force operating in the south of the country along with UAE troops.
There has been mounting international pressureto end the Yemen conflict that has killed more than 9,400people and displaced 2.8 million since March last year.
On Friday, the US military for the first time publicly acknowledged that American troops are operating inside Yemen to help pro-Hadi forcesand aSaudi offensive.
Defense Department spokesman Navy captain Jeff Davis said that a very small number of military personnel has in recent weeks been working with "Arab Coalition"forces.

The US is also offering an array of assistance to Saudi Arabia and its allies in their attacks inYemen, including air-to-air refueling capabilities, surveillance, planning, maritime security and medical help.
