Here's what happened in Aleppo while politicians in the West have been debating

On Monday night, Donald Trump and Hillary Clinton took part in the first presidential debate.

As several people pointed out, one rather important topic was absent.

In fact, on the same day, Britain's ambassador to the United Nations walked out of an emergency session of the Security Council after accusing Russia of committing war crimes.

Matthew Rycroft, in separate speeches to the council, said it as "difficult to deny" that both the Syrian regime and its Russian ally were committing war crimes:

After five years of conflict, you might think that the regime has had its fill of barbarity - that its sick bloodlust against its own people has finally run its course.

But this weekend, the regime and Russia have instead plunged to new depths and unleashed a new hell on Aleppo.

Boris Johnson also called the Syrian government's renewed attack on rebel-held areas of Aleppo "barbaric".

The bombing runs appear to be implementing explosives more suited to destroying military installations, known colloquially as 'bunker busters', in civilian areas, levelling buildings and causing casualties.

The UN said this weekend that airstrikes were reported to have killed 213 people in Aleppo province, 139 of them in eastern Aleppo.

At least 26 civilians were killed as the United Nations Security council met on Sunday, the Syrian Observatory for Human Rights reported.

As others have pointed out, Aleppo did not feature strongly in the Labour or Conservative party conferences either.

Hospitals in the area are reported to be overwhelmed, with not enough operating rooms or staff to deal with the injured.
