After one week of issuing a statement that claimed Pakistan may opt for nuclear weapon against India, Pak PM Imran Khan has once again threatened saying World War II like situation is likely, but “under the nuclear shadow” this time.

Vice President Mike Pence has said that the U.S. will keep up pressure on Iran as the nuclear deal between the Islamic Republic and world powers appears to be falling apart.

Donald Trump, addressing reporters, said that he and Putin discussed efforts to persuade North Korea to give up nuclear weapons, the political discord in Venezuela, and Ukraine during a call that stretched over an hour.

The country’s longest-range ballistic missile, Agni-V, will be inducted into the nuclear arsenal very soon, according to official sources.

The White House on Sunday issued a fresh warning to North Korea, saying that time is running out for a peaceful soultion between Kim Jong Un’s regime and the United States and its allies.

North Korea has successfully produced a miniaturized nuclear warhead that can fit inside its missiles, the Washington Post reported on Tuesday.

North Korea slammed China for criticising its nuclear weapons programme, saying it will never "beg" for Beijing's friendship, Pyongyang's state-run news agency said on Thursday.

United States President-elect Donald Trump on Monday responded on Twitter to North Korea's threats, stating that Pyongyang would not develop a nuclear weapon that could endanger US security.

In a bid to stop India's strong action against Pakistan's negligence to combat terrorism, Pakistani defence minister Khawaja Muhammad Asif on Wednesday said that Islamabad is open to using tactical devices if it feels its safety is in danger.
