MOSCOW (Reuters) - Russian companies hit by U.S. sanctions, including aluminum giant Rusal, have asked for 100 billion rubles ($1.6 billion) in liquidity support from the government, Finance Minister Anton Siluanov was quoted by Interfax news agency as saying on Friday.

The United States on April 6 imposed sanctions against several Russian entities and individuals, including Rusal 0486.HK and its major shareholder Oleg Deripaska, to punish Moscow for its suspected meddling in the 2016 U.S. election and other alleged "malign activity."

Rusal, the world’s second-biggest aluminum producer, has been particularly hard hit as the sanctions have caused concern among some customers, suppliers and creditors that they could be blacklisted too through association with the company.

A “temporary nationalization” is an option for some sanctions-hit companies, but not Rusal, Siluanov was quoted as saying. He did not name the companies he was referring to.

A Kremlin spokesman had said on Thursday that temporary nationalization was one of the options for helping Rusal.

According to another news agency, RIA, Rusal has only requested government support with liquidity and with demand for aluminum so far, Siluanov said.

RIA quoted the minister as saying the government was not considering state purchases of aluminum for now.
