The Syrian army launched a new assault on the country's largest city and rebel stronghold Aleppo on Sunday.
The city, home to two million people, came under heavy machine gun fire and shelling from President Bashar al-Assad's troops - forcing many local people to leave their homes.
Fierce fighting is also taking place in the Salaheddine district of the city.
ITV News' Harry Smith reports.
Syrina State television said Assad's forces were "cleansing the terrorist filth" from the country. The Free Syrian Army say they were forced to "strategically retreat" until the shelling ends.
