Ukraine has been under heavy bombardment by Russia since it began its offensive, but its air defenses have helped it take down drones and missiles.
Heavy fighting between IDF soldiers and Palestinian gunmen left at least three Palestinians dead and 28 injured.
The rocket engine was likely part of an anti-aircraft missile that was shot at an Israeli plane in the Yom Kippur War or the Six Day War.
The new systems include a new capability to use electronic warfare to detect drones and smart RF decoy.
The one-way drone was launched on Wednesday from the Jask area of Iran against a practice barge, the official said.
The latest action by North Korea came as US President Joe Biden's national security adviser, Jake Sullivan, was in Tokyo for meetings with his Japanese and South Korean counterparts.
Ukraine has been under heavy barrages from Russian cruise missiles, Iranian-made drones and artillery in recent days.
Russia, China, and Iran have all made various claims about possessing or working on developing such advanced missiles.
Russia launched four cruise missiles on the city, the South command of Ukraine's Armed Forces said.
The Post has learned that the next step in this process, German lawmakers release of advance payments of up to 560 million euros next week, is still only “most likely” and not yet a done deal.
