A suicide bomber wounded two bystanders in the Kazakh city of Aktobe when he blew himself up inside the offices of the state security services on Tuesday
President Nursultan Nazarbayev, who has ruled Kazakhstan for 20 years, was re-elected by a landslide in April on a platform of economic growth and stability. He prides himself on lasting peace among the 140 ethnic groups that call Kazakhstan home.
But media reports in recent months have identified several Kazakhstani citizens among radical groups operating in Russia's North Caucasus region and other republics of Central Asia.
Militants from Aktobe have been detained or killed in recent months in Dagestan, a southern Russian republic where rebels want to establish an Islamic state, local media have reported.
Analysts have also warned that Central Asian militants, after years fighting in Afghanistan and Pakistan, are filtering back across the region's porous borders to their homelands.
Tajikistan's army has been fighting insurgents in the country's mountainous east since an attack on a military convoy killed 28 troops last September, shortly after suicide car bombers attacked a police station in the country's second city.
Several radical Islamist groups have stated their objective of creating a Muslim caliphate incorporating large swathes of Central Asia, a region twice the size of Saudi Arabia.
"Not a single country in the region is immune," said Lilit Gevorgyan, analyst at IHS Global Insight. "Secular governments are their number one enemy."
Het uiteindelijke doel is natuurlijk om de controle te krijgen over de techniek van de Russische Sojoez-raketten in Kazachstan om deze om te kunnen bouwen tot kernraketten waarmee islamisten dan iedere plek ter wereld kunnen raken.
