Operation Spring Shield (Turkish: Bahar Kalkanı Harekâtı) was a cross-border military operation carried out by the Turkish Armed Forces (TSK) in the Idlib Governorate of northwestern Syria against the Syrian Armed Forces and allied militias. The operation was launched on 27 February 2020 in direct response to the Balyun airstrikes, aiming to address the escalating situation in the region.
According to Turkish Defense Minister Hulusi Akar, the primary objective of Operation Spring Shield was to achieve a ceasefire agreement within the framework of the Astana talks and to establish stability in the Second Northern Syria Buffer Zone. Additionally, the operation sought to prevent the mass migration of people from Idlib to the Turkish border, a pressing humanitarian concern.
On 5 March, Turkey and Russia signed a ceasefire agreement in Moscow, marking a step towards de-escalation in the region.

## Background

On 27 February 2020, during the Dawn of Idlib 2 Operation, Turkish Army positions in Balyun, Idlib Governorate, came under attack from airstrikes allegedly conducted by the Syrian Air Force and the Russian Air Force. Resulting in the deaths of 36 Turkish soldiers, with a reported number of wounded ranging from 36 to 60.
The following day, Russia denied it had carried out the airstrikes and stated that it had made efforts to halt the Syrian military's firing to facilitate the safe evacuation of the Turkish troops. Russia said that the Turkish forces should not have been present in the area, where "counter-terror operations" were underway, and criticized Turkey for failing to notify them about the soldiers' presence in advance. On the contrary, Turkey maintained that Russia was well aware of the locations of Turkish troops, as the two countries regularly communicated about this matter.
