Concerned about the safety of Indians residing in the wildfire-hit US state of California, Leader of the Opposition Lal Kishenchand Advani on Wednesday spoke to Prime Minister Manmohan Singh [Images] to enquire about their wellbeing.

Advani telephoned Dr Singh to find out whether the government had any information about Indians affected by the raging fire in southern California and any steps were being taken to ensure their safety.

California has a sizeable Indian population, majority of them businessmen from Gujarat.

The prime minister informed Advani that he did not have any information off-hand and would get back to him, sources said.

More than half a million people have been evacuated from their homes in California, about 500,000 in San Diego county alone, as massive fire, which broke out on Sunday, continued to wreak havoc.
