A senior Iranian commander said the Islamic Revolution Guards Corps (IRGC) plans to hold a security, defensive and rescue drills in Iran's capital Tehran, Press TV reported on Monday.

The IRGC commander, Brigadier General Mohsen Kazemeini, said that brigades from several units of IRGC will participate in the two-day drills, codenamed Imam Jafar Sadeq, according to the report.

The drills were due to be held in September but, later, were postponed to October 11-12 due to some considerations, the semi- official Fars news agency reported on Monday.

As regards the specification of the exercises, Kazemeini stressed the up-to-date nature of the exercises and said the drills have been designed and planned based on enemy's current conditions, according to Fars.

Several IRGC brigades will simultaneously carry out the exercises in different parts of the capital during the drills, he was quoted as saying.

Western countries including the United States and Israel suspect that Iran's nuclear activities aim at weapons which the Islamic republic denies.

Israeli Prime Minister Benjamin Netanyahu on Sunday urged the United States to set a clear red line on Iran's disputed nuclear program.

"I think the issue is how to prevent Iran from completing its nuclear weapons program. They're moving very rapidly to completing the enrichment of the uranium that they need to produce a nuclear bomb. In six months or so, they will be 90 percent of the way there," Netanyahu said on a CNN program.

The United States and Israel have not ruled out the possibility of attacking Iran's nuclear facilities.
