Iran’s Defense Minister Gen. Hussein Dehghan, told the channel that the liquid-fuel missile "will obviously boost the strategic deterrence capability of our armed forces”.
He said the missile, named Emad or pillar in Farsi, was a technological achievement for Iran – able to be controlled until the moment of impact and to hit targets "with high precision”.
The Iranian television showed footage of the huge missile being launched in a desert area, but it did not elaborate on the range of the missile or the specifics of the test firing.
This is the first test of a ballistic surface-to-surface missile by Iran since UN Security Council Resolution 2231 in July, which endorsed a landmark nuclear deal reached between Iran and world powers.  
Since 1992, Iran has emphasized a self-sufficient and indigenous military production industry, producing missiles, tanks and light submarines.  
Iran already has surface-to-surface missiles with a range of 2,000 kilometers (1,250 miles) that can hit Zionist targets and U.S. military bases in the region.
"The Emad missile is able to strike targets with a high level of precision and completely destroy them ... This greatly increases Iran's strategic deterrence capability," Dehqan said at a televised news conference.
"We don't ask permission from anyone to strengthen our defense and missile capabilities," he said.
"Our leadership and armed forces are determined to increase our power and this is to promote peace and stability in the region. There is no intention of aggression or threats in this action," he added.
Anthony Cordesman, a researcher at the Center for Strategic and International Studies in Washington, wrote in January that the Emad would have a range of 1,700 km (1,060 miles), 500 meters (1,650 feet) accuracy and a 750 kg (1,650 pound) payload.
It is a variant of the liquid-fuelled Shahab-3 missile, which has been in service since 2003 and has a similar range.
"The Emad represents a major leap in terms of accuracy. It has an advanced guidance and control system in its nose cone," the occupying regime of Israel’s missile expert Uzi Rubin said.
In August, Iran unveiled a new short-range missile named Fateh-313, which it said also offered improved precision over its predecessor, as part of an apparent drive to upgrade the accuracy of its missile arsenal.
"What has become increasingly clear is Iran's desire to enhance missile accuracy and lethality, a priority that very likely supersedes the need for seeking longer-range missiles," Elleman said.
The Fateh-313 has solid fuel, allowing it to be set up and launched faster than liquid-fuelled missiles, and a range of 500 km.
Improvements in accuracy could let Iran use its missiles in a wider variety of roles, for example by targeting military bases or economic assets rather than population centers.
The statement issued by Iraq's "war media cell" said Baghdadi was "transported in a vehicle" after the strike but added that "his health status was unknown".
"It's hard to confirm, there is definitely a psychological war going on between Iraqi intelligence and ISIL," Iraqi analyst Ihsan al-Shammari said.
"But even if they just hit his convoy, that would show a real improvement in the field of intelligence," he said.
The Iraqi ISIL chief is said to have been born in the city of Samarra in 1971 but little is known about the man, who has a $10 million U.S. bounty on his head.
Baghdadi apparently joined the insurgency that erupted after the 2003 U.S.-led invasion of Iraq, at one point spending time in an American military prison in the country's south.
His whereabouts have been the subject of constant speculation since his only public appearance as ISIL boss last year, at a mosque in the Iraqi city of Mosul days after the proclamation of a cross-border "caliphate".
 In Syria meanwhile Syria troops backed by Russian airstrikes made progress on two fronts but were battling other terrorist groups.
They were gaining ground on two fronts: in central Hama province around the Damascus-Aleppo highway and in the northern part of regime stronghold Latakia province.
In Hama, government forces had taken three villages east of the highway and were seeking to also secure control of an area to its west.
"This offensive is intended to confront the rebels in the Sahl al-Ghab plain that is at the intersection of Hama, Latakia and Idlib provinces," said Rami Abdel Rahman, director of the Syrian Observatory for Human Rights monitor.
Alawites from the same sect Abu Baklras Assad live in the south and west of the strategic 1,000 square kilometer (385 square mile) plain, while the north and east are mostly Sunni.
In recent months, terrorist have sought to capture parts of the area, advancing particularly from Idlib province, which is held by the Army of Conquest alliance that includes Al-Qaeda affiliate Al-Nusra Front.
In Moscow, Russia's defense ministry said Sunday that its fighter jets had hit 63 targets in Syria in the last 24 hours and reported it had intercepted radio traffic showing "growing panic" among ISIL terrorists.
