The US has expressed its concern over India’s recent successful underwater K4 missile launch.
“So we continue to urge all states with nuclear weapons to exercise restraint regarding their missile and nuclear capabilities,” Toner said when asked about recent ballistic missile test by India.
He said the State Department official had shared its concerns with New Delhi.
The Defence Research and Development Organisation (DRDO) flight-tested an underwater-launched missile called K-4 with a range of about 3,000 km on March 24.
Nearly 10 development trials of K-15 missile have already been completed from pontoons submerged in the Bay of Bengal over the past few years.
