Southern California authorities respond to a leak of an unknown chemical from a tank

LOS ANGELES (AP) — Authorities in Southern California responded to a slow leak from a chemical tank on Tuesday but quickly got it under control.

The substance and the leak's origin remain unknown, Los Angeles County Fire Department spokesperson Kaitlyn Aldana said.

Three people on scene declined transport to a hospital, she said.

Photos posted to social media showed what appeared to be an orange haze or mist in the sky.

La Habra Mayor Jose Medrano urged residents to shelter in place and said some streets were being evacuated.

Luis Gomez, who manages a pickleball program nearby, said he could see an orange cloud rising in the sky. He called police and was told anyone within a mile radius of the location is under an evacuation order.

“They said, ‘if you’re inside the one-mile (radius), you have to leave right now,’” Gomez said, adding he’s closing down his program for the rest of the day

The area is a mix of residential neighborhoods and industrial warehouses about 10 miles (16 kilometers) north of Anaheim.

Kylian Mbappe and Erling Haaland are off the mark in the Champions League as Real Madrid and Manchester City kicked off their campaigns with wins Tuesday.

Mbappe gave record 15-time champion Madrid an early lead en route to 2-1 victory over Inter Milan at the Santiago Bernabeu.

Haaland scored both goals as 2023 winner City beat Porto 2-0.

Madrid and City are expected to be among the main challengers to back-to-back defending champion Paris Saint-Germain this season and both will be relying on their star strikers.

Mbappe's goal after 14 minutes was his 71st in European club soccer's top competition, and Haaland took his tally to 59 in 59 appearances in the Champions League.

Borussia Dortmund beat Villarreal 3-2, and Real Betis won by the same score at Lille.

Aston Villa also won 3-2 over Club Brugge and AEK Athens sealed a 1-0 win over LASK.

PSG begins its campaign on Wednesday against Slovan Bratislava.

Aston Villa put its domestic problems behind it with a win over Club Brugge.

Victory in Belgium ended Villa's winless and goalless start to its 2026-27 season, after early struggles in the Premier League.

John McGinn recorded the first goal of the Champions League campaign with a sweeping low shot from an angle in the 11th minute. Hugo Vetlesen equalized for Brugge, but Emiliano Buendia and Nicolas Jackson put Villa 3-1 up by the break.

Nicolo Tresoldi scored for the home team with a 61st-minute penalty, but Villa held on for the win.

Villa coach Unai Emery will hope victory kickstarts his team's season after the summer departures of star players Morgan Rogers, Ollie Watkins, Ezri Konsa and Emi Martinez.

His much-changed team lost to Brighton and Arsenal in the Premier League and picked up its first point of the season with a goalless draw against newly promoted Hull on Saturday. It had recorded only one shot on target in those three games.

AEK Athens beat LASK 1-0 thanks to Razvan Marin's first-half free kick.
