A Russian plane accidentally dropped a bomb on Russia-occupied territory in Ukraine, an official said. It's the second such incident this month.

• Russian forces launched a massive missile and drone attack against Ukraine on Monday.
• During the attack a plane accidentally dropped a bomb on an occupied town in Ukraine, an official said.

A Russian plane accidentally dropped a bomb on Russian-occupied territory in Ukraine, a local Moscow-backed official said in a Telegram post on Monday.

Leonid Pasechnik, the head of the self-proclaimed Luhansk People's Republic, said the plane dropped a FAB-250 bomb on the eastern town of Rubizhne, which is located in Russia-occupied Luhansk.

"While carrying out combat operations, a Russian Air Force aircraft made an emergency release of a FAB-250 warhead over the city of Rubizhne," he said, per a translation provided by The Moscow Times.

No one was injured during the incident, and residents of nearby houses were evacuated, Pasechnik said.

He added that a group from the Interior Ministry, as well as representatives of the Emergency Situations Ministry and the military commandant's office, were on-site, per a translation provided by the Kyiv Independent.

It is the second such incident in less than a week.

Last Tuesday, a Russian plane accidentally dropped munition on the village of Petropavlovka in Russia's Voronezh region during an attack on Ukraine, the Russian Defense Ministry said, per the state-owned news outlet TASS.

Six buildings suffered damage, the defense ministry said, but no one was hurt.

This latest incident happened as Russia launched a wave of hypersonic and cruise missile attacks against Ukraine, Valerii Zaluzhnyi, the commander in chief of Ukraine's Armed Forces, said in a Telegram post on Monday.

Russia also suffered similar mishaps last year, like when it shot down one of its own prized Su-35 fighter jets in October, bombed the Russia-occupied city of Nova Kakhovka in September, and hit the Russian border city of Belgorod in April.

Meanwhile, Russia has been trying to increase its stockpile of cruise missiles, which Ukraine has struggled to intercept, the Institute for the Study of War reported last Thursday.

National Security Council spokesman John Kirby said last Thursday that Russia has acquired "several dozen" ballistic missiles from North Korea and had used them against Ukraine.

Russia is also likely looking to Iran to acquire more of these weapons, the ISW said.
