In Zaporizhzhia, the densely populated city close to the front line, the security situation is deteriorating.

It was five in the morning when Anna Holovchenko was woken up by glide bombs hitting the suburbs of her home city of Zaporizhzhia in eastern Ukraine. Security has deteriorated sharply there in a matter of weeks. Zaporizhzhia is a mere 24km (15 miles) from the front line, but is still home to some 750,000 people and the war is feeling closer than ever. An hour later drones flew over Anna's house in a second wave of attack and Ukrainian air defences tried to bring them down. "I realised I'm not getting any more sleep and started getting ready for work," she said. Numerous buses, petrol stations, schools, government offices and residential houses have been hit by Russian drones and bombs in recent weeks. Acting mayor Regina Kharchenko told the BBC that during one particularly intensive attack she "did not go to the shelter, but when it got too loud I took cover in the toilet". A Shahed drone crashed not far from Anna's office with a big bang, and another drone struck a cable, taking down the internet. "That's just another ordinary day in Zaporizhzhia," she said. Their city is the administrative capital of Zaporizhzhia region, one of five regions in Ukraine's south and east that Russia claims as its own. The Zaporizhzhia nuclear power plant, Europe's largest, is located almost 50km southwest of the city in part of the region under Russian occupation.
