Marco Chan, a former pilot and senior lecturer at Buckinghamshire New University, told BBC Verify that the rise in awareness of air disasters is being further fuelled because "accidents are getting increasing exposure from social media platforms".

Dmitry Peskov, Putin's spokesman, said the comments were "connected to an emotional overload of everyone involved".Germany's chancellor, Friedrich Merz, meanwhile said that Ukraine's allies had removed all range limits on supplied arms, amid reports he would give Kyiv Taurus missiles.

Trump's comments followed Russia's largest combined aerial attack since its full-scale invasion of February 2022. At least 13 people were killed and dozens injured in Ukraine during the night between Saturday and Sunday after Russia fired 367 drones and missiles.Between Sunday evening and Monday morning, Russia launched 355 drones against Ukraine, killing 10. The Ukrainian air force said it was the largest attack yet conducted with drones alone.Peskov said the latest aerial assaults were a response to Ukrainian attacks on Russia's "social infrastructure".

The Russian defence ministry said that air defence systems destroyed 20 Ukrainian drones over several Russian regions.Volodymyr Zelensky, Ukraine's president, said on Sunday there was no "military sense" to Russia's aerial attacks - rather they were "an obvious political choice... by Putin, a choice by Russia... to continue the war and destroy lives."

In an apparent response to the Russian attacks over the weekend, German chancellor Merz said there were "no longer" range restrictions on arms supplied to Ukraine.

"This means that Ukraine can now defend itself, for example, by attacking military positions in Russia... with very few exceptions, it didn't do that until recently. It can now do that," Merz said."It was so empathetic, it gave a response that you'd think was from a human that you've known for years […] And it did make me feel valued."

His experiences chime with a recent study by Dartmouth College researchers looking at the impact of chatbots on people diagnosed with anxiety, depression or an eating disorder, versus a control group with the same conditions.After four weeks, bot users showed significant reductions in their symptoms – including a 51% reduction in depressive symptoms - and reported a level of trust and collaboration akin to a human therapist.

Despite this, the study's senior author commented there is no replacement for in-person care.Aside from the debate around the value of their advice, there are also wider concerns about security and privacy, and whether the technology could be monetised.
