North Korea's nuclear weapons program since 1984
Pyongyang has carried out 23 missile tests this year, the most ever
TOKYO -- North Korea and the U.S. are continuing to push each other's buttons.
North Korean Foreign Minister Ri Yong Ho said Monday in New York that, "In light of the declaration of war by Trump all options will be on the operations table of the supreme leadership of [North Korea]."
Ri made the comment in response to a tweet by President Donald Trump on Saturday, in which he suggested North Korea's leaders "won't be around much longer."
"We have not declared war on North Korea," White House spokeswoman Sarah Huckabee Sanders told reporters later.
Yet the successive provocations have raised tensions, as North Korea continues to develop its nuclear and missile programs.
North Korea's latest missile launch on Sept. 15 was Pyongyang's 23rd missile test this year, according to government announcements and data from the Center for Strategic and International Studies.
North Korea has already exceeded last year's count of 21 missile launches, its highest annual tally since 1984.
Here is a timeline of the country's missile launches and nuclear tests dating back three decades, to the days of Kim Il Sung.
