A district in the southern Indian state of Tamil Nadu has constructed walls to seal the border with its neighbouring state, Andhra Pradesh, amid fears over the spread of Covid-19.

The walls, measuring about 5ft tall, were erected at two entry and exit points along the border on Sunday to prevent car traffic between Tamil Nadu's Vellore district and Andhra Pradesh's Chittoor district.

An official from Vellore district said that the move was meant to check the entry of migrant workers who sometimes enter the state without valid permission.

"Since the chances of getting detected at the main border crossing is high, some people tend to use little-noticed locations in remote places," the official told PTI news agency.

But some authorities have told local media that it is a "temporary measure" to keep tabs on the flow of vehicular traffic between the two states.
