The United States on Friday imposed new sanctions on eight Venezuelan officials and increased to $25 million the reward it is offering for the arrest of President Nicolas Maduro on the day of his inauguration to a third term following a disputed election last year.

Venezuela's authoritarian President Nicolás Maduro was sworn in for a third six-year term on Friday, following an election that many in the international community and the opposition considered rigged.

The United States issued new Venezuela-related sanctions on Friday, including measures targeting state oil company PDVSA chief Hector Obregon, according to a notice on the Treasury Department's website.
