New drone footage shows the level of destruction of Aleppo from Syrian and Russian bombings. Following a failed one-week truce brokered by the US and Russia, airstrikes have begun daily in the besieged city.

In its airstrikes, Russia has been using “bunker buster” bombs to flatten apartment buildings. The bombs were designed to destroy military bunkers. Some say this is the first time they have been used in an urban setting.

In recent months, the Syrian government has cornered rebels in other cities into surrendering after years of carnage and starvation. Some say the government wants the rebels in Aleppo to surrender soon as well.
