- Whether it's the exploding coronavirus,

mysterious fires at nuclearand military facilities,

or protests, Iran's rulingIslamic clerics are facing

unprecedented challenges as a regime tries

to maintain an iron grip on the nation.

On Monday, the government executed a man

it convicted of spying for theCIA and Israeli intelligence.

Mahmoud Mousavi-Majdreceived that sentence

for allegedly passinginformation to the CIA

about the whereabouts ofGeneral Qasem Soleimani.

The powerful leader was killed

in a US drone strike earlier this year.

- This is a regime that's facing really

a possible rebellion in the near future,

a regime officials talk about.

And so, they're executing a lot of people

to put fear into the public.

- [George] The execution follows a string

of mysterious fires andexplosions around the country.

On Sunday, fires broke outat a military installation

near Tehran, a shipyard in Bushehr,

and a key power plant connected

to Iran's Natanz nuclearfacility in Isfahan.

Similar incidents have happenedacross Iran since June.

- This cannot be a coincidence.

This cannot be just a series of accidents

without malicious intent from someone.

- [George] Some pointingto Israel's ongoing overt,

and at times, covert waragainst the Islamic republic.

- Israel specifically istrying to stop the transfer

of very advanced, precise munitions

to the regime's proxies like Hezbollah,

and also wants to slow downthe Iranian nuclear program.

- [George] This as PresidentTrump reportedly gives

the CIA green light tolaunch more offensive

cyber attacks to cripple or destroy some

of Iran's critical infrastructures.

All this against the backdropof ongoing government protests

and a remarkable revival that's witnessing

thousands of Muslimsturning to Christianity

in the midst of COVID-19.

- That's why we callthis a pandemic of hope.

- [George] Mike Ansari runsMohabat TV, one of the most

popular Christiansatellite channels in Iran.

The ministry reports it is recording

10 times more online salvationsthan this time last year.

- We're registering around3,000 professional decisions,

personal decisions by Irani Muslims

to leave Islam for Christianityduring this revival.

- [George] Ansari says that's3,000 people each month

who have decided to follow Jesus Christ

since the pandemic began in March.

- People in Iran are just not happy,

the way their economy's going,

the way the government is robbing them

of their natural resourcesand exporting Shia Islam

to the neighboring countries.

So, they just don'ttrust their government.

- [George] The large numberof people leaving Islam

is causing a backlash against the church.

Dozens of Christians have also been

arrested and imprisoned for responding

to the gospel message since March.

- During these criticaltimes for the regime,

there's a tendency historically

for the regime to really crack down

on religious communitieslike Chrisitian comm.

Some see that today.

- Iran is one of the world'smost dangerous places

for Christians, yetChristianity is growing faster

in Iran than in any othercountry in the world.
