Unknown gunmen shot dead Revolutionary Southern Movement (RSM) leader on Monday in the southern port city of Aden, few days after the assassination of his comrade.
Two motorcyclists opened fire at Abdullah Hussein al-Qaheem out of his house on the 50-m Street in Aden, seat of the Yemeni internationally-recognized government, local sources told Debriefer.
This is the second time a RSM leader is assassinated within one week, after last Thursday murder of Rami Mohamed al-Masa'abi, also at the hinds of unknown gunmen, in Aden.
The RSM (a component of the Southern Movement calling for south Yemen to be separated from north) condoled Qaheem as "one of the SM heroes since its launch in 2007."
The RSM council called upon official authorities to identify the killers and clarify the successive accidents, including murder, targeting the RSM.
Since its liberation from Houthis in July 2015, Aden has been suffering destabilized security.
Authority of the government is claimed by many local powers, some backed by UAE and others loyal to Hadi, that possess up to heavy weapons and control vast swaths of Aden and some other Yemeni provinces.
The port city also saw assassinations of many civilians, activists, journalists and religious, community, security, military and political leaders, including former governor Ja'afar Mohammed Sa'ad.
The official security authorities are trying to stabilize Aden's security, but some of those powers do not receive directives from government.
The Emirati-backed Southern Transitional Council often says Aden and other provinces in the south are under its forces' control.
The UAE is a key player in a Saudi-led coalition that intervened militarily in the country in March 2015 to reinstate the internationally recognized Yemeni government of President Hadi.
