Two more persons succumbed to gunshot wounds in Assam's Guwahati, taking the toll in police firing during violent protests against the citizenship law to four, officials said on Sunday.

Gauhati Medical College and Hospital superintendent Ramen Talukdar told PTI that one person died on Saturday night and another person lost his life on Sunday morning.

'Ishwar Nayak died last night and Abdul Alim succumbed to his injuries this morning,' he said.

Twenty-seven people have been admitted to the hospital with bullet injuries since Wednesday, he added.

However, protesters claimed that five persons have died in police firing during the agitations against the contentious law.

Two persons, identified as Sam Stafford and Dipanjal Das, were shot dead on Thursday in Guwahati, which turned into a garrison town with army, paramilitary and state police personnel present in every nook and corner.

However, protesters and All Assam Students Union (AASU) have been claiming that three persons died of bullet injuries that day.

'They (government) have unleashed their oppressive machinery on people, killing five minor students and injuring many others with bullets. It is clear that the Sarbananda Sonowal government will be brought down,' AASU president Dipanka Kumar Nath said.
