Two foreign aid workers were killed in Ukraine on Sunday when Russian shelling struck a van carrying Ukrainian NGO staffers, as nearly three dozen drones were launched at Kyiv, littering debris across several city districts.

A van carrying four volunteers from the Road to Relief NGO, which helps evacuate wounded people from the front lines, flipped over and caught fire after being struck by shells near the town of Chasiv Yar.

The organization’s director, Emma Igual, 31, died in the attack, Spain’s foreign minister Jose Manuel Albares told The Telegraph.

“A projectile fell on a vehicle in which this Spanish citizen was traveling,” Albares said.

“She was working there at an NGO helping with the humanitarian situation in Ukraine and we have verbal confirmation of her death.”

Canadian citizen Anthony Ihnat was also killed in the attack, the group said on Instagram.

German medical volunteer Ruben Mawick and Swedish volunteer Johan Mathias Thyr were seriously injured, according to the Sunday post.

“Earlier this morning around 10AM, four of our Road to Relief team members left from Slovyansk toward Bakhmut direction to assess the needs of civilians caught in crossfire in the town of Ivanivske, Bakhmut Region, Donetsk Oblast,” it read.

“On their way in, passed Chasiv Yar, their vehicle came under Russian attack. Proceeding a direct hit, the vehicle flipped over and lit on fire.”

Also on Sunday, Ukraine’s air force said the military destroyed 26 out of 33 drones launched by Russia targeting Kyiv and the surrounding region.

Witnesses told Reuters they heard at least five resounding blasts across Kyiv during the attack, where videos showed the nighttime sky lit up as the strike commenced.

“Drones came onto the capital in groups and from different directions,” Serhiy Popko, head of Kyiv’s city military administration, said on Telegram.

Kyiv Mayor Vitali Klitschko said debris from downed drones fell on five different districts, injuring one person.

The head of Kyiv’s military, Serhii Popko said the Iranian-made Shahed drones caused no risk to the person’s life. At least one high-rise apartment was also damaged in the drone strike.

Kyiv region Governor Ruslan Kravchenko wrote on Facebook that an unspecified infrastructure facility and eight houses had been damaged in the overnight strikes.

There was no immediate comment from Russia about the latest attacks.

A Russian attack on Wednesday killed 17 people in the eastern city of Kostiantynivka, Ukrainian officials said.

Russian air defence forces on Sunday claimed to have destroyed a Ukraine-launched drone over the Bryansk region, in south-western Russia. No damage or casualties were immediately reported.
