As reports circulated Wednesday about the alleged "Momo Challenge" that encourages children to harm themselves, YouTube issued a response saying no videos of the sort had been published recently on its platform."We want to clear something up regarding the Momo Challenge: We’ve seen no recent evidence of videos promoting the Momo Challenge on YouTube. Videos encouraging harmful and dangerous challenges are against our policies," YouTube said in a tweet. "If you see videos including harmful or dangerous challenges on YouTube, we encourage you to flag them to us immediately. These challenges are clearly against our Community Guidelines."Facebook, which owns WhatsApp — a platform reportedly targeted by the challenge — also issued a response."We care about the safety of our community and want to provide assistance for people in distress. As outlined in our Community Standards, we don't allow the promotion of self-injury or suicide and will remove it when reported to us," the statement read. "We also provide people who have expressed suicidal thoughts, and people who want to reach out to a friend who may be struggling, with a number of support options and resources. These global tools and resources were developed with the help of over 70 mental health partners around the world and we’re continuously improving them to build a safer and more supportive community on Facebook." 1402

As unrest wavered through the United States on Saturday, one protest had a different way of protesting: Through dance. In Newark, New Jerseys, dozens of Black Lives Matter protesters joined in a dance of the famous dance song “Cupid Shuffle” on Saturday. The scene showed a stark difference from events taking place in other cities, many of which had looting and rioting on Saturday. Video of Saturday's dancing protest has gone viral, with more than 8 million views on Twitter by Sunday evening.Saturday's protest was one of many being held in major cities through the US in response to the death of George Floyd, who died while in police custody on Monday. The city’s police department called Saturday’s protest in Newark “peaceful.” The world needs to know about what happened in Newark today. A Black city, with a Black mayor (who marched with us), and many Black owned businesses. 100% peaceful demonstrations. Anger was allowed to be expressed in a healthy way and wasn’t met with force. 1006

Rural areas received around 5 to 6 inches of rain.No injuries were reported as of Wednesday morning, Lewis told CNN. 1104
