Reuters - Special courts set up in a drive against financial crime have sentenced three people to death, state television reported on Sunday, as the country faces renewed U.S. sanctions and a public outcry against profiteering and corruption.

The special Islamic revolutionary courts were set up last month to try suspects quickly after Supreme Leader Ayatollah Ali Khamenei called for �swift and just� legal action to confront an �economic war� by foreign enemies.

Judiciary spokesman Gholamhossein Mohseni Ejei, quoted by state TV, said the courts handed down out death sentences to three defendants after convicting them of �spreading corruption on earth�, a capital offence under Iran�s Islamic laws.

Mohseni Ejei did not name the three but said the sentences would have to be upheld by the supreme court before being carried out, the TV reported.

Iranian officials have accused arch-foes the United States and Israel, as well as regional rival Saudi Arabia and government opponents living in exile, of fomenting unrest and waging an economic war to destabilize Iran.

Mohseni Ejei said 32 other defendants were sentenced to jail terms of up to 20 years, the official news agency IRNA reported.

In May the United States pulled out of a 2015 deal between world powers and Tehran under which international sanctions on Iran were lifted in return for curbs on its nuclear program.

Washington has reimposed a number of sanctions on Iran, and it is planning to impose heavier sanctions in November aimed at the Islamic Republic�s oil sector.

The rial currency has lost about 70 percent of its value since April under the threat of revived U.S. sanctions, with heavy demand for dollars among ordinary Iranians trying to protect their savings.

The cost of living has also soared, sparking sporadic demonstrations against profiteering and corruption, with many protesters chanting anti-government slogans.
