In Afghanistan, all mobile phone services in southern province of Helmand have been shut down on Taliban orders. MTN, one of Afghanistan's four mobile phone operators, said the Taliban has threatened to attack its operations if it did not switch off the signal. The head of MTN's legal department Mohammad Naser Nasery said they decided to obey the orders as they cannot afford for their antennae and other facilities to be destroyed. He added that other operators had also followed suit. A Taliban spokesman said it had ordered the shutdown because of a recent increase in attacks on its fighters. Taliban militants regularly demand that mobile phone companies switch off their networks at night, fearing that NATO-led forces can track them through phone signals. There have been a number of attacks on mobile phone towers across the country. Helmand is one of the most volatile provinces of Afghanistan and its capital Lashkar Gah is among the seven places for transition to Afghan security forces this July.
