The US has announced an increased $25m (£20.4m) reward for information leading to the arrest of Venezuelan President Nicolás Maduro on the day he was sworn in for a third six-year term in office.
The inauguration ceremony was overshadowed by recrimination from the international community and Venezuelan opposition leaders.
Rewards have also been offered for information leading to the arrest and or conviction of Interior Minister Diosdado Cabello.
A new reward of up to $15m for Defence Minister Vladimir Padrino has also been offered.
The UK also issued sanctions on 15 top Venezuelan officials, including judges, members of the security forces and military officials.
The Foreign, Commonwealth and Development Office said those sanctioned were responsible for “undermining democracy, the rule of law, and human rights violations”.
Foreign Secretary David Lammy went on to describe Maduro’s regime as “fraudulent”.
