Two people were killed and at least two others injured on the evening of June 11 in the shelling of the Suzemka area in Russia's Bryansk region near the Ukrainian border, Acting Regional Governor Yegor Kovalchuk said, adding that another seven were wounded in an attack on petrol stations in Starodub about 110 km from Suzemka [1, 2]. Separate from those attacks, a five-year-old boy was injured in a drone strike in Bryansk region [1].

On the Ukrainian side, a Russian drone attack in the northern Sumy region killed a 44-year-old woman who worked as a rail station operator and seriously wounded a 33-year-old female station attendant, according to Oleksandr Pertsovkyi, head of Ukrainian Railways. The woman died en route to a shelter during the strike [1, 3]. Three others were injured in a drone attack earlier on June 11-12 in the southern Ukrainian city of Mykolaiv [1, 3].

Early June 12 drone strikes targeted Russia’s Tatarstan region, injuring three people and hitting industrial sites, though production was not suspended, local officials said [3]. The city of Togliatti in Samara region declared a drone attack regime following strikes that day, with Governor Vyacheslav Fedorishchev alerting residents [3].

Russian authorities accused Ukrainian forces of cross-border attacks on civilian areas and infrastructure in Bryansk, blaming them for escalating violence [2]. In response, Russia plans to strengthen border defenses to reduce such incursions [2].

Al Jazeera's Audrey MacAlpine described the strikes as part of Ukraine’s "logistics lockdown," targeting fuel infrastructure, bridges, and logistics to disrupt Russian frontline operations [3]. Governor Kovalchuk said a total of 2 people were killed and 10 injured in Bryansk's attacks [1].

The timeline shows shelling in Bryansk's Suzemka and Starodub on June 11 evening, with drone attacks in Tatarstan and Togliatti early on June 12, alongside the Russian drone strikes in Ukraine's Sumy and Mykolaiv around the same time [1, 3, 2].

Officials expect increased border security measures soon. The drone attack regime declared in Togliatti remains active as authorities assess ongoing risks [3].
