Kazakhstan has tightened security in its southern provinces in the wake of a deadly bombing that killed five police officers and two civilians, including an apparent suicide bomber, in the city of Taraz.
A combined shooting-and-bomb attack took place on Saturday in the southern Kazakh city of Taraz, the Interfax-Kazakhstan news agency reported.
Troops stationed along the country's southern border had intensified patrols and traffic controls, the news agency Kazakhstan-Novosti said.
The two police officers who sustained bullet injuries were in a serious but stable condition, the Interfax news agency reported.
At least one of the explosions was thought to have occurred outside the national security committee building.
An unknown individual attacked a weapons shop, stealing two Saiga rifles and killing a security guard, the interior ministry said in a statement quoted by Interfax-Kazakhstan.
He then escaped in a vehicle, shooting dead two police officers on his way. When finally apprehended, the gunman detonated his charge, killing himself and a traffic policeman, the agency reported.
"After being arrested, the wounded criminal blew himself up and as a result a member of the traffic police was killed," the interior ministry said.
Bekbolat Orynbekov, the head of the Taraz administration, told the news agency: "Investigators, the national security committee and prosecutors are working at the scene."
Interfax-Kazakhstan said that its own correspondent in the city had seen one corpse being put into a black body bag by the local authorities. A nearby shop was also burgled.
