Ukraine war updates: Drone strikes fuel depot in western Russia

A fuel depot in the western Russian city of Oryol was hit by a drone strike, causing a fire, the regional governor said early Tuesday. It was one of several Ukrainian attacks overnight.

"A fuel and energy complex facility was attacked. Special services are working on the spot to contain the fire. There were no casualties," regional governor Andrey Klychkov wrote on the messaging app Telegram.

Local media reported that the attack occurred at around 3:00 a.m. local time (0000 GMT). According to an emergency services official quoted by Russian state news agency RIA Novosti, a tank with oil products caught fire.

An oil processing unit in the town of Kstovo in Russia's Nizhny Novgorod region was also on fire after a drone attack, Gleb Nikitin, governor of the region, said.

Russia's air defense systems, meanwhile, also destroyed a Ukraine-launched drone flying towards Moscow, Mayor Sergein Sobyanin said.

Ukrainian drones also attacked the Russian region of Belgorod, near the Ukrainian city of Kharkiv, on Monday night, causing no injuries, according to the region's governor.

Rebuilding Ukraine's scientific infrastructure will cost more than $1 billion, UN says

Reconstruction of Ukraine's scientific infrastructure will cost more than $1.26 billion (€1.15 billion), the UN's scientific and cultural organization said.

According to a UNESCO study, 1,443 buildings and laboratories belonging to 177 scientific institutions have been destroyed.

In addition to the buildings themselves, over 750 pieces of scientific and technical equipment have been damaged, with 643 items damaged beyond repair. This includes equipment used in a wide range of research activities.

The war, now in its third year, has also depleted the science sector of funds and dispersed Ukraine's scientists, displacing many within the country and sending others into exile.

The situation around the Institute for Safety Problems of Nuclear Power Plants, near the Russia-occupied Zaporizhzhia Nuclear Power Plant in Ukraine's southeast, is of particular concern, the report said.

The institute's essential equipment for monitoring the nuclear industry has been stolen or destroyed, representing a safety threat in the region and beyond, the report added.
