ntelligence has warned that Russia could invade Ukraine at any time, despite claims from the Kremlin that Russian forces are retreating from the border.
A number of nations have ordered nationals living in Ukraine to leave, as tension mounts on the border.
Although an invasion of Ukraine has not yet occurred, the threat is enough to hugely disrupt Christian missionary work in the country.
Sharyn Borodin, from Youth with a Mission, is currently in Poland after leaving her base in Ukraine.
She says the rising tensions are huge cause for concern when it comes to the work of her organisation.
She said: "Our largest base is currently not operating, because of the crisis - that's the base that's in Kiev.
"Our base will continue to be open come what may.
"However, in the last two months, we've had 30 students that have been on our base serving throughout the ministries of our base and they've all been repositioned because of the conflict.
"So you know, my husband and the other guy that we run that we direct the base with, they have this ongoing contest to see who has made them the most middle of the night border runs in the last month because of our teams feeling that they needed to reposition quickly.
"It's also interesting, that currently we have nine hospitality rooms in our building and about 20 hospital beds; at last count 20 of them are full.
"We've had four families from Canada and the United States that have moved here because they feel safer.
"Between them there's 12 children.
"So we have around 20 people in total right now, that we didn't plan to be with us, that would not normally be with us, but that are taking refuge in our area because of the proximity to the borders with the West.
"We've also had teams that were supposed to be coming to serve with us this spring, that we have cancelled because of the situation, so it vastly impacts us."
Despite the struggles, Sharyn says she's finding relief in the knowledge that the world is finally listening and that Christians are praying for the people of Ukraine.
The two countries have been at war in the East for almost a decade, and their history is extensive and incredibly complicated.
However, now - she believes - God will finally use the prayers to bring peace.
