Firefighters worked across the weekend to tackle smouldering roof insulation in the giant protective shelter which covers Chernobyl's unit 4 following the drone strike on Friday. Radiation levels in the area remain normal - the original protective shelter inside the giant structure did not suffer any damage.
International Atomic Energy Agency staff at the Chernobyl site say "radiation levels inside and outside remain normal and stable" after a drone was reported to have struck the roof of the shelter built over the remains of the reactor destroyed in the 1986 accident.
The State Nuclear Regulatory Inspectorate of Ukraine has given approval for the commissioning of the Solid Waste Retrieval Facility and Solid Waste Processing Plant at the Chernobyl nuclear power plant site.
The head of the State Nuclear Regulatory Inspectorate of Ukraine, Oleg Korikov, has urged against any further delays in the project to dismantle the unstable shelter facility, which was built at speed in 1986 to cover Chernobyl's damaged unit 4.
The area around the Chernobyl nuclear power plant is one of the places being looked at as potential locations for Ukraine's planned future wave of small modular reactors.
The next phase of the project has begun to study which parts of the shelter built rapidly around Chernobyl's unit 4 after the 1986 accident need immediate dismantling and which bits need stabilisation.
President Alexander Lukashenko told International Atomic Energy Agency Director General Rafael Mariano Grossi that Belarus would not "in our worst nightmare" seize Chernobyl and then be answerable for it.
