Several hundred protesters that had gathered outside the occupied SBU building proclaimed the "Luhansk People's Republic" on 27 April.
They demanded that Ukrainian government provide amnesty for all protesters, enshrine Russian as an official language, and hold a referendum on the status of the region.
They issued an ultimatum that stated that if Kiev did not meet their demands by 14:00 on 29 April, they would launch an insurgency in tandem with that of the Donetsk People's Republic.

As these demands were not met, 2,000 to 3,000 protestors stormed the Luhansk RSA building on 29 April.
Previously, only the SBU building had been targeted.
The building was unprotected on the exterior, but a group of riot police confronted the protesters in an inner courtyard of the building.
A brief standoff resulted, but the police did nothing to stop the protesters.
A Russian flag was raised over the building.
Several other buildings, including a police station and the local prosecutor's office were later seized.
Twenty separatist gunmen fired machine guns at the police station to force the officers within to surrender.
President Oleksander Turchynov responded to the loss of the buildings by demanding the immediate resignation of police chiefs in Donetsk and Luhansk.
By 2 May, however, pro-Russian protesters occupying the city council and the television centre had left, and the prosecutors office was freed following negotiations between authorities and separatists.

The next day, however, separatist leader and self-proclaimed mayor of Luhansk Valeriy Bolotov announced the formation of a "South-Eastern Army" to march on Kiev.
Bolotov also declared a state of emergency, introduced a curfew, a ban on political parties, and a mandate that local law enforcement officials must take an oath of allegiance to him.
In a video statement, he said "In case of not following this, you will be announced traitors of people of Luhansk and wartime measures will be taken against you".

A GAZ Tigr heavy armoured vehicle emblazoned with the emblem of the Liberal Democratic Party of Russia was seen parked outside the RSA building on 8 May, along with men in military gear and assault rifles.
Whilst speaking to OSCE monitors, the Deputy Governor of Luhansk Oblast said that the "security situation in the region is deteriorating due to activities of the separatists and criminal gangs".
Members of the OSCE special monitoring mission were later stopped at an 'illegal' checkpoint near the village of Shchastya, and held for three hours before being released.
