Security services in ex-Soviet Kyrgyzstan said Friday they had killed two members of what they claim was the cell of an international terror group during a nightime raid in the capital Bishkek.

The Kyrgyz State Committee for National Security (SCNS) refused to name "the international terror group" but said the two dead terror suspects were responsible for "particularly serious crimes" in the Central Asian state.

"The criminals put up fierce armed resistance and were eliminated," the SCNS statement said, adding the raid had taken place Thursday night.

"The cell members that were killed were involved in a number of particularly serious crimes including the murder of a policeman in the 8th district of Bishkek."

At least 500 Kyrgyz citizens including 122 women have joined up with the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group fighting in Iraq and Syria, the interior ministry said last month.
