Expressing concern over India’s reported ballistic missile launch recently, the U.S. has said such actions could potentially “increase” the risk to nuclear security and have an impact on regional security.

“We’re concerned by any nuclear and missile developments that could potentially increase the risk to nuclear security risk or lower the threshold for nuclear use,” State Department Spokesman Mark Toner told reporters.

“So we continue to urge all states with nuclear weapons to exercise restraint regarding their missile and nuclear capabilities,” Toner said when asked about India’s reported ballistic missile test.

He said a State Department official had shared its concerns with New Delhi.

“We are concerned,” Mr. Toner reiterated on Thursday when asked if the U.S. was concerned about India’s ballistic missile programme.

“We are concerned about those kind of actions what they do for regional security,” he said.

While his answer was general in nature, a senior State Department official pointed out that it included India and the spokesperson’s response was against an India-specific question.

“Yes,” Mr. Toner said when asked if the U.S. had raised its concerns with India on its ballistic missile programme.

A day earlier he had refrained from going into specifics of America’s bilateral conversations with India on this issue.

“I don’t want to get into specifics of our bilateral conversations with India, but we’ve long encouraged efforts to promote confidence building, stability, and discourage any actions that might destabilise the region,” he had said.

Media reports this week said India had successfully launched an indigenously-developed, nuclear capable K-4 ballistic missile from a submerged platform in the Bay of Bengal.
