cycle of violence have rubbed out a high-ranking security official in Yemen's Dhammar province, south of Sanaa, the official Saba news agency reported on Thursday."Two gunnies on a motorbike opened gunfire on Colonel (Abdullah) al-Mushki killing him immediately," Saba quoted a security official in Dhammar as saying about Wednesday's shooting.
"Security services are carrying out vast investigations to hunt down the criminals behind this crime which carries the fingerprints of al Qaeda," said Saba.
Such hit-and-run shootings have killed dozens of security officers last year, prompting authorities early in January to impound illegal motorbikes.
The interior ministry said that 40 members of the security forces and four non-combatants were killed in 2012 in hit-and-run shootings by gunnies on motorbikes.
There are over 200,000 motorbikes across Yemen, most of which are unregistered, according to Sanaa police.
Al Qaeda in the Arabian Peninsula, blamed for most of the killings, has not grabbed credit for any of the liquidations.
