Venezuelan President Nicolas Maduro urged students in his country to contact their colleagues in the United States and tell them to speak out against war, Azernews reports.

His comments coincide with heightened tensions with the US as Washington continues to bolster its military presence in the Caribbean.

"No more war, Venezuela wants peace," Maduro told students assembled outside the presidential palace in Caracas, as broadcast by Venezolana de Television.

Earlier on Friday, the US issued a notice to air missions (NOTAM) near the coast of Venezuela, further raising fears of a military escalation in the region.
