KYIV (Reuters) -Overnight Russian air attacks wounded eight people, set a private business on fire and damaged residential buildings around Ukraine, local officials said on Tuesday. Ukraine's air force said it shot down 65 drones and 28 more did not reach their targets in the barrage.

Russia launched a hundred Shahed and imitation drones at Ukraine. The Air Defense Forces of the Armed Forces of Ukraine destroyed 65 of them. The drones were launched from the Russian cities of Orel,

Videos showed fireballs over a facility in Ryazan, 110 miles southeast of Moscow. Kyiv is seeking to disrupt Russian military logistics and put pressure on the country’s economy by striking its oil industry.

Russia launched a barrage of drones in an overnight attack on Ukraine on Friday, killing three civilians and damaging residential and commercial buildings, officials said.

Both Russia and Ukraine are using “jam-proof” drones that use fiber-optic cables. However, these drones have vulnerabilities that both countries will soon exploit.

Russia and Ukraine exchanged large drone attacks on Sunday night into Monday, with alleged Ukrainian UAVs forcing flight restrictions at three Russian airports.

Russia and Ukraine are turning to fibre-optic drones in an effort to get around drone jamming. Experts say the technology could have far-reaching implications beyond the war zone because drone jammers are one of the few tools security agencies can use to bring down rogue or suspicious drones.

Ukrainian military on Sunday said it thwarted 50 of 72 drones launched by Russia overnight and attacked one of Russia’s largest oil refineries. Military and civilian authorities did not immediately report casualties or damages.
