Five people have been killed in a shooting at the Molson Coors Brewing Company campus in Milwaukee, Wisconsin state, local officials say. They say the gunman died from “self-inflicted wounds”. The man – a 51-year-old Milwaukee resident – worked for the company. His motives were unclear.

The shooting occurred in the early afternoon while hundreds of employees were still at work. Milwaukee Mayor Tom Barrett said it was a “tragic day for the city”. Speaking at a news briefing shortly after Wednesday’s shooting, he described it as a “horrific act”. Meanwhile, Milwaukee police chief Alfonso Morales said that the five victims were all employees of the brewing company. He praised the way the city’s police, FBI officers and firefighters responded to the attack. As the incident unfolded, nearby schools and businesses were locked down, local media report.(BBC)…[+]

Barack Obama has made a rare intervention in the 2020 White House race to decry a “despicable” racially charged attack ad against Joe Biden. A pro-Trump group put out the clip that twists Mr Obama’s own words in order to undermine the Democratic contender. Mr Biden is hoping the black vote in South Carolina’s primary on Saturday will revive his campaign. Though Mr Biden was his vice-president, Mr Obama has observed neutrality in the race, refusing to endorse a contender. Joe Biden is one of eight candidates remaining in the race to become the Democratic candidate who will take on President Donald Trump, a Republican, in November’s election.

The ad – entitled South Carolina, Joe Biden Can’t Be Trusted – was broadcast on TV stations in the southern state before Tuesday night’s Democratic debate in Charleston, formerly America’s largest slave port. “Joe Biden promised to help our community,” says a female narrator in the video. “It was a lie.”

She introduces audio from Mr Obama in which he says: “Plantation politics. Black people in the worst jobs, the worst housing. Police brutality rampant. “But when the so-called black committeemen came around election time, we’d all line up and vote the straight Democratic ticket. “Sell our souls for a Christmas turkey.(bbc)…[+]

The Mexican government says it regrets a ruling by the US Supreme Court that bars the family of a Mexican boy who was killed in 2010 from suing the US border patrol agent who shot him. The boy, Sergio Hernández, was shot dead on Mexican soil by US border patrol agent Jesús Mesa, who was on the US side of the border. The court ruled that the parents could not use US courts to sue Mr Mesa. The Mexican government says it is concerned it could set a precedent. The incident happened on the border between El Paso, Texas, and Juárez, Mexico. Agent Mesa was on a bicycle patrol on the US side of the border and was reportedly alerted to the presence of people smugglers.

Sergio Hernández, 15, was with a group of youths in the dry bed of the Rio Grande when Agent Mesa approached.

The international border runs through the middle of the concrete culvert built to contain the river but is unmarked.(BBC)…[+]
