At least 10 people have been killed after a vehicle drove into a large crowd in New Orleans, a city in Louisiana, United States.

The incident occurred on Wednesday afternoon in the French Quarter, a popular tourist area, when a car sped down Bourbon Street.

Witnesses told CBS News that the driver reportedly got out and began shooting at pedestrians. Police returned fire, and two officers were injured in the exchange.

Anne Kirkpatrick, the city’s police superintendent, described the attack as “very intentional”.

“This man was trying to run over as many people as he possibly could,” she said.

Kirkpatrick said attack began at 15:15 local time (21:15 GMT), adding that most of the victims appeared to be local residents, but the identities of those killed or injured are still being determined.

She said numbers could change, but confirmed 10 people were killed and at least 35 others injured.

She said it is unclear how many victims are tourists and how many are locals but added that she believed that the majority are local to New Orleans.

The superintendent said the Federal Bureau of Investigation (FBI) will take over the investigation into the incident.

Althea Duncan, FBI agent, clarified that the shooting was not a terrorist incident, but noted that “improvised explosive devices” were found on scene.

Duncan said the FBI is working to find out if they are “viable” devices and urged the public to stay away from the area.

Jeff Landry, governor of Louisiana, described the incident as a “horrific act of violence”.

Landry said he is praying for all the victims and first responders at the scene.

A Seoul western district court has issued an arrest warrant against impeached South Korean President Yoon Suk Yeol following his botched martial law declaration.

It is the first time authorities have sought to detain a sitting South Korean president.

It is unclear when authorities would attempt to take Yeol into custody. January 6 was given as the deadline to execute the warrant.

“The arrest warrant and search warrant for President Yoon Suk Yeol, requested by the Joint Investigation Headquarters, were issued this morning,” the Joint Investigation Headquarters, which includes officials from the Corruption Investigation Office for High-ranking Officials (CIO), police, and the defence ministry, said in a statement on Tuesday.

The warrant comes after Yeol, who is being investigated for power abuse and inciting an insurrection, ignored three summons in the last fortnight.

The president’s legal team has called the warrant “illegal and invalid” and said they would challenge it in court.

Flights have been cancelled and delayed at UK’s busiest airports due to heavy fog.

Flights at Stansted Airport were reportedly affected by the weather conditions on Saturday and Sunday. There were also delays at Heathrow, Luton and Manchester Airports.

A spokesperson at Nats, the UK’s main air traffic control provider, said temporary air restrictions will continue on Sunday as fog envelopes airfields.

“Temporary air traffic restrictions are therefore in place at airfields with low visibility to maintain safety.

“Our teams are working closely with the airports and airlines to minimise disruption but passengers should check the status of their flight with their airline.”

The UK Meteorological Office has issued warnings effective Monday and Tuesday — with up to 140mm of rain, 20cm of snow and 60mph winds possible in the worst-affected areas during the run-up to New Year’s Eve.

Thousands of passengers arriving at London Gatwick Airport overnight reportedly experienced long delays.

An easyJet flight from Enfidha in Tunisia due at 11.10pm was over four hours late, and a British Airways jet from Lanzarote touched down at 3.03am, almost four hours behind schedule.

A Gatwick spokesperson said “temporary air traffic restrictions have been put in place due to fog causing poor visibility”.

The airport apologised for any inconvenience, adding that delays could last all day.

Manchester Airport reportedly had 22 cancellations, including six departures and arrivals.
