Doctors have called for an urgent international effort to combat a "pandemic of bad drugs" that is thought to kill hundreds of thousands of people globally every year.

A surge in counterfeit and poor quality medicines means that 250,000 children a year are thought to die after receiving shoddy or outright fake drugs intended to treat malaria and pneumonia alone, the doctors warned.
