Iran successfully tested its own model of a missile system that Russia declined to supply amid concerns Tehran might be seeking nuclear weapons, a military official was quoted as saying on Thursday.

Russia infuriated Iran in September when it cancelled the S-300 missile order after heavy lobbying from the United States and Israel, which said the system could be used to help Iran shield its nuclear facilities from possible future air strikes.
State-run Press TV quoted a commander of Iran's elite Revolutionary Guards as saying Tehran had adapted another Russian-made missile system to perform like the more sophisticated S-300.
'We have developed the system by upgrading systems like the S-200 and we have tested it successfully,' Brigadier General Mohammad Hassan Mansourian said, according to Press TV's website.
Some Western analysts doubt Iran's ability to replicate the S-300, a precision, mobile, long-range air defence system that can detect, track and destroy ballistic missiles, cruise missiles and low-flying aircraft.
However, some Western officials suspect Iran's development of more sophisticated missiles could serve the goal of attaining a deliverable nuclear weapon.
