Timeline of the war in Donbas (2014)

This is a timeline of the war in Donbas for the year 2014.

April –June

 * 7 April – At 3:30 am, pro-Russian activists stormed the SBU offices in Donetsk and Luhansk. They did not initially make clear demands, but later called for a referendum on independence from Ukraine by 11 May. The militants took control of the SBU armoury and armed themselves with automatic weapons, while other supporters brought bricks and debris to erect barricades. They initially numbered 1,000, but subsequently thinned. In an address on the Ukrainian national television channel, interim President Oleksandr Turchynov stated that the current unrest in eastern Ukraine was "the second wave" of a Russian operation to destabilise Ukraine, overthrow the government and disrupt planned elections and represented an attempt by Russia to "dismember" Ukraine. He vowed to launch a major "counter-terrorism" operation against separatist movements.
 * 8 April – In Luhansk, separatists occupying the SBU building declared themselves the "Luhansk Parliamentary Republic". According to Ukrainian security officials, the separatists planted mines in the building and took 60 people hostage.

 * 12 April – Fifty-two armed militants led by Igor Girkin (retired FSB colonel) attacked the executive committee building, the police department, and the Security Service of Ukraine offices in Sloviansk. His militia was formed in Crimea and consisted of volunteers from Russia, Crimea, and other regions of Ukraine (Vinnytsia, Zhytomyr, Kyiv) and many people from Donetsk and the Luhansk region. Two thirds were Ukrainian citizens. The majority of men had combat experience. Many of the Ukrainians had fought in the Russian Armed Forces in Chechnya and Central Asia. Others fought in Iraq and the former Yugoslavia with the Ukrainian Armed Forces.  Girkin's original intention was to replicate the Crimean scenario (seizure of the territory by Russian army). According to Girkin, nobody fought for the Donetsk People's Republic or the Luhansk People's Republic, everybody initially wanted to join Russia. Girkin flew a Russian flag at his headquarters and his men were perceived as Russian forces by the local population. Girkin believed that the Russian Armed Forces and the Russian state would quickly follow and the Donbas would become a republic within Russia. In Kramatorsk, in the course of a pro-Russian rally, protestors overpowered a police line and occupied the building of the local executive committee, where they hoisted the new-proclaimed republic's flag.
