KARACHI, April 7: Mobile companies have not yet responded to the call of Sindh Minister for Environment and Alternative Energy Dr Saghir Ahmed for shifting mobile phone towers out of the city.

Studies have revealed that these communication towers are emitting harmful electromagnetic waves in the air, causing pollution which badly affects human health.

The Pakistan Telecommunication Authority issues licenses to cellular companies for operations while the city government is authorised to allow them for setting up of towers in the city but it is not clear which authority would take action against mobile companies for not shifting the towers.

The issue seems to be a legal battle now as cellular companies have signed contracts with owners of buildings where mobile towers had been erected.—PPI
