AP� The latest on protests in Iran (all times local):

11:15 p.m.

Syria has expressed solidarity with Iran where clashes between protesters and security forces over the past days have left several people dead and wounded.

Syria is Iran�s strongest ally in the Arab world and Tehran has been a main backer of Syrian President Bashar Assad since the country�s conflict began in 2011, pumping hundreds of millions of dollars into the Syrian economy.

A Syrian Foreign Ministry statement released Tuesday blasted the U.S. administration and Israel for expressing support to Iran�s protesters. It blamed the U.S. and Israel for destabilizing the region.

The ministry said Iran�s sovereignty should be respected and no one should interfere in Tehran�s internal affairs.

�Syria is confident that Iran�s leadership, government and people will be able to defeat the conspiracy,� the Syrian ministry said.

The head of Tehran�s Revolutionary Court has reportedly warned that arrested protesters could potentially face death penalty cases when they come to trial.

Iran�s semi-official Tasnim news agency quoted Mousa Ghazanfarabadi on Tuesday as saying: �Obviously one of their charges can be Moharebeh,� or waging war against God. That�s a death penalty offense in Iran.

Ghazanfarabadi also was quoted as saying some protesters will come to trial soon on charges of acting against national security and damaging public properties. He also stressed that attending rallies not sanctioned by Iran�s Interior Ministry, which oversees police, was illegal.

Iran�s Revolutionary Court handles cases involving alleged attempts to overthrow the government.

Iranian state television is reporting that nine people have been killed overnight amid nationwide protests and unrest.

The report Tuesday puts the death toll in six days of demonstrations to at least 20 people.

State TV says six rioters were killed during an attack on a police station in the town of Qahdarijan. It reported that clashes were sparked by rioters who tried to steal guns from the police station.

State TV says an 11-year-old boy and a 20-year-old man were killed in the town of Khomeinishahr, while a member of Iran�s paramilitary Revolutionary Guard was killed in the town of Najafabad. It says all were shot by hunting rifles.

The towns are all in Iran�s central Isfahan province, some 350 kilometers (215 miles) south of Tehran.
