tate English language Press TV on Wednesday aired pictures of what it said was the successful launch of a Sajjil-2 missile, a high-speed, surface-to-surface missile with a range of about 1,200 miles (1,930 kilometres).
That range places Israel, Iran's sworn enemy, well within reach and could reach as far away as southeastern Europe with greater precision than earlier models.
Iran is also known to possess a medium-range ballistic missile known as the "Shahab-3", which means "shooting star" in Farsi, with a range of at least 800 miles (1,300 kilometres).
In 2005, Iranian officials said they had improved the range of the "Shahab-3" to 1,200 miles (2,000 kilometres). The Sajjil-2 missile is Iran's most advanced two-stage surface-to-surface missile and is powered entirely by solid-fuel while the older Shahab-3 uses a combination of solid and liquid fuel in its most advanced form, which is also known as the Qadr-F1.
Solid fuel is seen as a technological breakthrough for any missile programme as solid fuel increases the accuracy of missiles in reaching targets.
Iran launched an arms development programme during its 1980-88 war with Iraq to compensate for a US weapons embargo. Since 1992, Iran has produced its own tanks, armoured personnel carriers, missiles and a fighter plane. The country has intensified its domestic missile development in recent years, raising concerns of the US and its allies at a time when they accuse the country of seeking to build a nuclear weapon.
Iran denies it wants to build a bomb, saying its nuclear programme is only for civilian purposes, aimed at generating electricity.
