The Ministry of Interior has called on the public to "reject all acts of lawlessness, riots and vandalism" that the separatist Southern Transitional Council called for on Wednesday.
In a statement, the Ministry said the STC's call on its supporters to "seize all revenue-generating institutions" from the government's hand is an irresponsible call.
The statement said: "The Yemeni people live in exceptional and too hard conditions as a result of the war the Houthi coupists have been imposing for three successive years. Everyone should feel that with a sense of national and moral responsibility, and should abstain from any acts of undermining the relative security that we have."
The Interior Ministry vowed it won't "stay with arms crossed in front of any acts of lawlessness and arson that target the state institutions and the state of law and order under any pretext."
