JERUSALEM (JTA) — Israel condemned last week’s nuclear test by North Korea.

“Israel condemns North Korea’s nuclear test, and joins the international community in expressing concern of the danger that this act poses to regional stability and international peace and security,” said a statement issued by Israel’s Ministry of Foreign Affairs on Tuesday.

The hydrogen bomb test, which North Korea said was successful, “must be met with a swift response by the international community. A clear message must be sent to (North Korea) and to other countries, that such activities are unacceptable and cannot be tolerated.”

North Korea announced the test on Jan. 6, after South Korea recorded a seismic event located near the site where the neighboring country has previously conducted nuclear tests.

Israel has neither confirmed nor denied that it has nuclear weapons and has not signed the Nuclear Non-Proliferation treaty, though it is popularly understood that Israel has dozens of nuclear weapons.
