Pakistan suspends mobile networks over fears of attacks

Pakistan's authorities are suspending mobile phone services in major cities to prevent sectarian violence during key Shia Muslim commemorations.

More than 90% of bombs are detonated by attackers using phones, officials say.

In some areas, motorbikes carrying passengers have been banned because of fears that this is how attackers could be brought to their targets.
