Hello! Here’s what’s happening on Wednesday.

1. One person is dead and four are injured in a shooting at YouTube’s California headquarters. The shooter has been identified as 39-year-old Nasim Aghdam, who had previously criticized the video platform.

2. A YouTube employee had his Twitter account hacked to spread a hoax about the identity of the shooter. The company has been criticized in the past for promoting conspiracy videos that claim several mass shootings were a hoax.

3. US President Donald Trump rolled out a list of $50 billion worth of Chinese products that will face new tariffs. Experts say Trump’s decision will likely provoke a response from the Chinese and could push the two countries toward an all-out trade war.

4. British military scientists can't prove that the nerve agent used to poison ex-spy Sergei Skripal was made in Russia. Theresa May accused Russia of masterminding the assassination three weeks ago, and several countries have expelled their Russian diplomats in response.

5. North Korea appears to be preparing a satellite launch that could jeopardize US talks. President Trump has agreed to a meeting with North Korea, but his advisors may also be preparing for war.

6. President Trump is reportedly not considered a "criminal target" in the Russia investigation. Still, special counsel Robert Mueller remains focused on Trump, and has requested a sit-down interview.

7. US stocks rebounded as investors shook off a recent tech sell-off and trade war anxieties. The S&P 500 was up 1.15% following a strong production report form Tesla.

8. Facebook took down more than 200 accounts and pages run by a notorious Russian trolling group. Last year, Facebook admitted it had detected Russian activity on its platform that took place around the 2016 presidential election.

9. Saudi Arabia will fine couples $130,000 for snooping through each others' texts. The anti-snooping laws are part of an increased focus on cyber crime and hacking under the Prince's Vision 2030 plan.

10. India's Prime Minister withdrew an order to crackdown on journalists accused of spreading fake news. The government previously said it would suspend journalists found guilty of producing fake news.
