Russian secret services have confirmed the killing of their 'most wanted' man, the Islamic terrorist leader and Chechen warlord Doku Umarov.



Umarov, who was once dubbed 'Russia's Bin Laden', was 'neutralised' in a 'combat operation' which left dozens of terrorists dead, according to the country's Federal Security Service (FSB) announced.



A website sympathetic to the Islamic insurgency in the North Caucasus had reported that Umarov had been killed on March 18, but Moscow had not previously confirmed the report, until today.



'Most wanted': Russian secret services have confirmed the killing of Islamic terrorist leader Doku Umarov

Umarov , who had called for attacks on this year's Winter Olympics in Sochi, was the leader of the

Caucasus Emirate organisation which aims to establish an independent Islamic State in the region.

The group, which is blamed attacks in Moscow in 2010 and 2011 that killed a total of 77 people, is also listed as a terrorist organisation by the United States.



Alexander Bortnikov, the head of the FSB, told a meeting of Russia's National Anti-Terrorism Committee: 'As a result of a combat operation, the activity of the head of the terrorist organisation Caucasus Emirate, Umarov, was neutralised,'



Mr Bortnikov 's comments were distributed in a video clip, one day after President Vladimir Putin delivered a speech in which he said there must be no let-up in the fight against the militants.

'Neutralised': Moscow claims that Umarov was killed in a 'combat operation' that left dozens of insurgents dead Atrocity: Umarov's Caucasus Emirate group claimed responsibility for the bomb that caused the November 2009 Nevsky Express train derailment that left 27 dead The group is also thought to have been behind three suicide bombings in the southern Russian city of Volgograd which killed 41 people in 2013, including this attack on a trolleybus Umarov united local militant groups in the North Caucasus under his command in 2007 and led the violent struggle to create a caliphate in the patchwork of mainly Muslim provinces sitting on Russia's southern border. Bortnikov gave no details of the combat operation, however the state-funded RT news channel said dozens of terrorists had been killed and hundreds of militants and their supporters were detained. In the first three months of 2014, Russia’s security services conducted 33 counter-terrorist operations and have eliminated 13 warlords and 65 active members of the terrorist underworld, with over 240 terrorists have been arrested, RT reported.

The death of Umarov is a breakthrough for Putin in the fight against the Caucasus Emirate, although it already has appointed a new leader who identified himself as Ali Abu Mukhammad in a video posted on You Tube. Putin crushed a separatist rebellion in Chechnya when he first rose to power 14 years ago but the insurgency has since spread to neighbouring Dagestan.
