JOHN YANG: Good evening.

I'm John Yang.

Spring, the season of rebirth and renewal has reminded us that it can also be the season of death and destruction.

At least 25 people are dead and dozens more injured after a tornado ripped through a rural Mississippi Friday night over an hour northwest of Jackson.

This afternoon, Mississippi Governor Tate Reeves declared a state of emergency as officials continue to comb through the damage.

Homes leveled, power lines downed, neighborhoods destroyed.

This is the scene thousands of Mississippi residents woke up to this morning.

EDGAR O'NEAL: Complete and utter devastation.

Just houses, roofs ripped off of houses, walls tucked down from houses, trees up.

NO NAME GIVEN: Hey, you all need help over there?

JOHN YANG: The storm pummeled this stretch of the Mississippi Delta with wind gust up to 80 miles per hour, and hail the size of golf balls.

NO NAME GIVEN: We ran, got in the bathroom, in the tub with my wife, and off through pillows over us, and we could hear stuff hitting the roof.

JOHN YANG: The tornado was so intense that radar images left the meteorologist for WTVA in Tupelo nearly speechless.

NO NAME GIVEN: Oh, man.

Dear Jesus, please help them.

JOHN YANG: Early this morning, Mississippi Governor Tate Reeves dispatched search and rescue teams to sift through the rubble for survivors.

Damage from the storm stretches over 100 miles across the state with debris and wreckage blocking roads.

NO NAME GIVEN: Everybody is helping everybody.

Not in just this part of town.

It's everywhere.

Everybody is being, helping, and praying, (inaudible) everybody.

JOHN YANG: The National Weather Service says that on Sunday there's a chance of severe thunderstorms capable of producing more tornadoes across the Southeast.

As other states brace for impact, Mississippi hopes to find more survivors.

Russian President Vladimir Putin says he will move tactical nuclear weapons into Belarus.

The former Soviet Republic had deactivated its nukes and sent them to Russia following the collapse of the Soviet Union.

Putin, speaking on state television today, said nuclear storage facilities would be finished by July.

Belarus has been a staging ground for Russian troops in its invasion of Ukraine.

And Gordon Moore, the cofounder of Intel, has died.

He was known as one of the fathers of Silicon Valley and for Moore's law.

His 1960s prediction that computing power would roughly double every two years for the foreseeable future, making computers smaller, faster, and cheaper.

It's held true for decades and is a driving force of technological and social change and economic growth.

Moore was 94 years old.
