At least 11 people, including an 8-year-old boy, have lost their lives in Uttar Pradesh as the protests against the Citizenship (Amendment) Act turned violent in the state, officials said on Saturday.

Four deaths were reported from Meerut district, while the boy was killed in a stampede in Varanasi when a violent mob was being chased by police personnel on Friday, they said.

After Friday prayers, six people were killed as protesters clashed with the police at several places in the state. They hurled stones and torched vehicles, the officials said.

There have been reports of firing on police personnel deployed to maintain law and order, they said.

Director General of Police O P Singh on Friday said that 50 policemen were seriously injured in the violence.

Violence during the anti-Citizenship (Amendment) Act protests has so far claimed lives in Bijnor, Sambhal, Firozabad, Kanpur, Varanasi and Meerut in the state.

Clashes with police were also reported from Bhadohi, Bahraich, Amroha, Farurukhabad, Ghaziabad, Varanasi, Muzaffarnagar, Saharanpur, Hapur, Hathras, Bulandshahr, Hamirpur and Mahoba districts.

At many places, police used lathis, lobbed teargas shells and, according to some officials, rubber bullets when they failed to contain angry mobs.

Internet services have been suspended across major cities in Uttar Pradesh, following the state government orders.

 All schools, colleges and universities across Uttar Pradesh will remain shut on Saturday as well. An order was issued to this effect on Friday night, a government spokesperson was quoted as saying in an official statement.

The government had earlier ordered closure of all schools on Thursday and Friday owing to severe cold wave condition.

The order comes at a time when protests against the Citizenship (Amendment) Act have rocked several parts of the state, claiming at least six lives in violence and arson.
