Former U.S. President George H.W. Bush died Friday aged 94.

Family spokesman Jim McGrath confirmed his death in a brief statement but did not specify a cause.

Bush served as the U.S.'s 41st president following his role as President Ronald Reagan's vice president for both of his terms in the 1980s.

He had suffered in recent years from a myriad of health problems.

His son, George W. Bush, who served as the 43rd president of the United States, issued a statement in which he said he and his siblings "are saddened to announce that after 94 remarkable years, our dear Dad has died".

"George H.W. Bush was a man of the highest character and the best dad a son or daughter could ask for," he said.
