Dec. 2 (UPI) -- Pope Leo XIV spoke out Tuesday on migrant issues and rising tension between the United States and Venezuela.

The pontiff hinted at danger and "signals" of threats of possible U.S. military intervention and "invasion" of Venezuela on his return trip to Rome from Lebanon, saying "so we must see."

"On the one hand, it seems there has been a telephone conversation between the two presidents," he told reporters on board. "On the other hand, there is this danger, this possibility, that there could be an action, an operation."

Leo ended his nearly week-long trip in Beirut at a waterfront mass that drew at least 150,000 worshippers.

On Tuesday, the Roman Catholic Church head addressed a number of global topics.
