“We deliver items to various locations, including this hospital in Chervonohrad, police stations in Lviv and Lutsk, and schools.”
Ms Gutierrez claimed that after the Russian army captured some volunteers, those delivering food and aid were now escorted by police.

“When I hear the siren, it’s very scary because we don’t know what to do,” she explained.
“It’s impossible to adjust to.”
Ms Gutierrez and other volunteers are seen in photos and videos loading supplies into a car, ready for distribution in Ukraine.

“The Ukrainian people regard us volunteers as heroes,” she continued.
“Sometimes I feel like crying when I see families breaking apart – men over 18 years old can’t get out of Ukraine.

“But we can’t cry because we’re here to support these families.”
It is unknown how many foreigners have travelled to Ukraine to help in humanitarian capacities.
However, in a March 6 update, the Ukrainian government stated that it had received 20,000 applications from foreigners seeking to fight Russia.
