Meanwhile, a Venezuelan police officer who led a helicopter attack last week on the country’s Interior Ministry and Supreme Court released a new video Wednesday vowing a second wave of attacks. Oscar Pérez apparently recorded the video from hiding, after abandoning his helicopter during his escape.

Oscar Pérez: “There are 30 million Venezuelans that go with truth. And they will have to imprison the entire country in order to silence our mission, our duty, our patriotism, our fight. We will go to the street, and we will be there with you. You are not alone.”

Opposition leaders have accused President Maduro of working with Pérez to stage last week’s attacks, which damaged government buildings but did not injure anybody. Maduro called the attack “terrorism” and an attempted coup d’état.
