 The African students trapped in Ukraine have said they may face extra challenges as they try to escape. They've been blocked from getting off trains or and barred from crossing borders to neighboring countries. Roughly 20% of Ukraine's foreign students are Africans, including 4,000 Nigerians. African activists and students have been raising awareness of their plight through the Twitter hashtag Africans in Ukraine. They've also created a group chat on WhatsApp and Telegram to organize assistance. Some of my friends are still there and I'm very worried. I text them to know what they're doing, if they are food or water because right now the stores are closed. And the attacks are getting worse. Very, very worse and hopefully they get out of Ukraine safe and no harm comes upon them. We could see the bomb in the tree where it exploded right near my house. So if I did not leave that day, it would have been a problem for me to leave. And now as people are trying to leave, the transportation is getting more expensive. They are saying $700 to get to Uzkhorod from Lviv for a taxi, so it's getting really, really expensive. Most people have left the city and if you're right there alone, it's when you have to communicate with people and also get things like I said, resources and all of that. And a place to sleep. And a place to sleep. People haven't slept in days. Yeah, people haven't slept. And most people go to the underground metros, the metro station to stay down. It is very cold, uncomfortable and it's really not a nice place to be at night. It is very cold, it is very, very cold in there. Yeah, not nice to be in. But we have no choice to stay there because we could hear the Bremlins in our city.
