1. Trade threats: Global markets are running scared at the prospect of another major escalation in the US-China trade war.
The US government said it was readying new tariffs of 10% on $200 billion worth of Chinese goods, releasing a list including fruit and vegetables, handbags and baseball gloves.
US stock futures were down by about 1%.
European markets declined in early trade, with many down by more than 1%. Most Asian markets ended the day in the red, with Chinese stocks down roughly 2%.
China's Commerce Ministry said that the Trump administration's announcement of new measures was "unacceptable." It warned that China would have to respond with "necessary countermeasures" but didn't provide details.
The VIX index, Wall Street's so-called fear gauge, shot up following the exchange.
2. Pfizer surprise: Pfizer (PFE) has confirmed that it will defer raising prices on multiple drugs after heavy pressure from President Donald Trump.
The pharmaceutical company's announcement came after Trump tweeted that he spoke with Pfizer's CEO and his own Health and Human Services secretary, Alex Azar.
"Pfizer is rolling back price hikes, so American patients don't pay more. We applaud Pfizer for this decision and hope other companies do the same," Trump tweeted.
The company said it made the decision "following an extensive discussion with President Trump."
Pfizer, which hiked prices on nearly three dozen drugs on July 1, said it will give the administration more time to work on its plan to overhaul the pharmaceutical supply chain.

3. Sky and Fox: 21st Century Fox (FOX) has reached a new deal to buy Sky (SKYAY) that values the UK broadcaster around £24.5 billion ($32.5 billion).
Fox is in a bidding war for Sky with Comcast (CMCSA), which launched an offer for the company in April.
Fox's new bid for Sky of £14 ($18.60) per share is 12% higher than Comcast's. But Comcast can still come back with another bid.
The contest is part of a wider fight between Disney (DIS) and Comcast to take over a large chunk of Fox.

The fine is the largest allowed under Britain's data protection law. Shares in Facebook dipped 1% in premarket trading.
