Iran’s Revolutionary Guard says it has lifted a self-imposed limit of 2,000 kilometers (1,200 miles) on the range of its ballistic missiles, suggesting the country may seek to develop missiles capable of reaching more distant targets as fears of renewed all-out war rise.

The comments by the spokesman of Iran’s paramilitary Revolutionary Guard came days after the country’s supreme leader, Ayatollah Mojtaba Khomeini, warned that “any kind and level of threat” from the US or Israel would face a response without geographic limits.

Asked at a Tehran news conference about the limit on missile ranges, Gen. Hossein Mohebbi said, “That restriction has been lifted for us.”

Iran is not known to have missiles that can go beyond the 2,000-kilometer (1,200-mile) limit. However, US officials have said technology from Iran’s space program can be repurposed to build intercontinental ballistic missiles.
