The president of Venezuela took part in an event with his supporters on Saturday, where he recalled British musician John Lennon and even went on to sing part of one of his iconic songs, “Imagine.”

Nicolás Maduro was delivering a rallying speech to a group of supporters in the populous Petare neighborhood on the outskirts of the capital, Caracas, when, in the middle of his remarks, he asked his communications minister, Alfred Nazareth, to remind him of the song’s name.

“What a beautiful song, the lyrics. For the young people, look up the lyrics. It’s an inspiration for all times,” the Venezuelan president said after hearing a passage of the song, which was played over the event’s sound system.

Maduro’s public appearance and his comments about seeking peace come as tensions with the U.S. rise amid the presence of warships in the Caribbean near Venezuela’s coast, which the Trump administration says are aimed at fighting drug trafficking.

The US military's 20th strike on a boat accused of transporting drugs has killed four people in the Caribbean Sea, the U.S. military said Friday, coming as the Trump administration escalates its campaign in South American waters.

The latest strike happened Monday, according to a social media post on Friday by U.S. Southern Command, which oversees military operations in the Caribbean and Latin America.

The latest strike brings the death toll from the attacks that began in September to 80, with the Mexican Navy suspending its search for a survivor of a strike in late October after four days.
