LOS ANGELES: Tens of thousands of people ordered to flee their homes as wildfires tore through Los Angeles were told on Thursday they would not be allowed back for at least a week till Jan 20 -with fears over electrocution, landslides and exposure to toxic materials.

Frustration is mounting among evacuees, who are angry over rules that prevent them from returning _ even to homes that survived the deadly blazes.

`There was a group chat where everyone was complaining, getting mad, saying, `why do they keep on locking us out of our homes?`` Ronnen Miz told local broadcaster KTLA.

But with 40,000 acres (16,000 hectares) burned in two ferocious fires, the situation is just too dangerous, officials said.

Electricity, gas and sewage lines are wrecked, there is toxic waste everywhere, and there is a growing threat of hazardous mudslides or landslips, officials said at a news conference.

`It`s going to be a while,` said Los Angeles county sheriff Robert Luna.

`Pm going to say at minimum, at least another week, and that`s an estimate, but I believe it`s going to be longer than that.

Sometime later, she found the car and its irreplaceable contents had been stolen.-AFP
