Three separate attacks using petrol bombs and other improvised devices took place in Thessaloniki in the early hours of Wednesday, according to multiple outlets. The blasts resulted in one death – Vagia Nestora, the 72‑year‑old mother of New Democracy politician Aphrodite (or Afroditi) Nestora – who suffered burns covering about 80 % of her body. Attackers ignited the fires with gas canisters or gas lighters.

Three people were injured in the attacks, reported by the New York Post. GreekCityTimes said that Aphrodite Nestora was hospitalized with first‑ and second‑degree burns to her arms and legs, plus inhalation injuries, while her father Panagiotis Nestoras was treated for breathing difficulties and smoke inhalation. Two other residents of the apartment building were also taken to hospital, and the fire spread to vehicles, causing serious injuries. GreekCityTimes identified the Charilaou district as the site of the firebombing and noted that the residences of Zisis Ioakimovits and Savvas Anastasiadis were also targeted, according to Athens‑Times.com.

Accounts differ on the exact timing of the attacks. The Sydney Morning Herald reported that all the attacks took place within a 15‑minute period, from 1 a.m. on Tuesday local time onwards, while Athens‑Times.com cited authorities estimating the attacks occurred between 4:18 a.m. and 4:35 a.m., a 17‑minute window. Reports also vary on the hospital to which Vagia Nestora was rushed: GreekCityTimes said Ippokrateio Hospital, whereas Athens‑Times.com said Hippokration Hospital. Age reports differ as well; while multiple sources listed her as 72, Athens‑Times.com reported her age as 70.

Responsibility for the Thessaloniki attacks is also contested. Some reports described the perpetrators as suspected anarchists, while others said the attackers remain unknown. Coordinated nighttime attacks in Athens and Thessaloniki set fire to banks, a Mercedes dealership, a car with diplomatic plates, a security‑company van and two state power corporation vehicles, according to the Sydney Morning Herald, which added that nobody was injured in the Athens attacks.
