<h1>Stop The War!</h1>
<p>On the 24th of February 2022 Russian armed forces invaded Ukraine and started war against a sovereign country. The attack came from both Russia and Belarus. Thousands of Ukrainian and Russian soldiers and hundreds of Ukrainian civilians, including women and children, have already been killed.</p>
<p><strong>If you protest</strong> against the war, <strong>you may get arrested</strong> for up to 15 years. Even if you just say that attacking another country with weapons is a war, you may be prosecuted the same way.</p>
<p>But <strong>if you close your eyes</strong> and stay quiet, <strong>you will be an accomplice</strong> to the mass murderer who claims to be your president.</p>
<h2>What do you choose?</h2>
<p>If you're connecting from Russia or Belarus then your government is actively blocking your access to independent information sources. To help you to know what's really happening, here is an uncensored list of recent news from variety of sources:</p>

<h1>Остановите войну! </h1>
<p>24 февраля 2022 года российские вооруженные силы вторглись в Украину и начали войну против суверенной страны. Нападение произошло как со стороны России, так и со стороны Беларуси. Тысячи украинских и российских солдат и сотни украинских гражданских лиц, включая женщин и детей, уже убиты.</p> <p>
<p><strong>Если вы протестуете</strong> против войны, <strong>вас могут арестовать</strong> на срок до 15 лет. Даже если вы просто скажете, что нападение на другую страну с оружием - это война, вас могут привлечь к ответственности таким же образом.</p>
<p>Но <strong>если вы закроете глаза</strong> и будете молчать, <strong>вы станете сообщником</strong> массового убийцы, который называет себя вашим президентом.</p>
<h2>Что вы выберете? </h2>
<p>Если вы подключаетесь к Интернету из России или Беларуси, то ваше правительство активно блокирует ваш доступ к независимым источникам информации. Чтобы помочь вам узнать, что происходит на самом деле, вот список переведенных новостей из разных источников без цензуры:</p>
