Welcome to the NewsHour. Tonight, the U.S. says its ceasefire with Iran is still holding,

but it was a violent day with the U.S. and Iranian militaries trading fire overnight.

And today, Iran struck Kuwait's main airport, killing one person and injuring dozens more.

The ceasefire is also being tested by the ongoing conflict in Lebanon, which has exposed rare public tensions between President Trump and Israel's prime minister.

Nick Schifrin begins his report with the new violence in the Gulf.

Inside Kuwait International Airport today, this is what ceasefire looks like.

Part of the passenger terminal clouded by dust and debris and the crackle of fire.

An airport employee points to the spot where he says Iranian drones made a direct hit.

The attack temporarily shut down the airport and shook America's Gulf allies who were advocating

for a U.S.-Iran diplomatic deal.

But there is no deal, and the attacks are increasing.

Today, Iran fired missiles at Kuwait and for the first time since the ceasefire began, Bahrain

and the headquarters of the U.S. Navy's fifth fleet.

The missiles either failed or were shot down, but the ceasefire is being strained.

Iran calls these launches a response to the U.S. striking this oil tanker's engine to enforce

the U.S. blockade of Iranian ports.

They were slightly provoked because we took a strong action for a different reason.

So they were reciprocating it.

Today in the Oval Office, President Trump also labeled Iran strikes a response to U.S. attacks,

even though the U.S. military called its strike self-defense after Iranian attacks.

And today, as he has repeatedly in the past, President Trump dangled the promise of a diplomatic

deal.
