Popular security committees of the Yemeni city of Aden on Sunday arrested 32 members of the Houthis.
The Houthis, on board of a public bus, were arrested before entering the city to take part in the Houthi attempts to seize control over the city.
Saudi Arabia and its allies have launched "Operation Decisive Storm" against Houthi targets after the group carried out an assault to seize Aden, where Yemeni President Abd Rabbuh Mansour Hadi is taking refuge.
