A former top terrorism official at the CIA has warned
that President Barack Obama's controversial drone programme is far too indiscriminate in hitting targets and could lead to such political instability that it creates terrorist safe havens.
Obama's increased use of drones to attack suspected Islamic militants in Pakistan, Afghanistan, Somalia and Yemen has become one of the most controversial aspects of his national security policy. He has launched at least 275 strikes in Pakistan alone; a rate of attack that is far higher than his predecessor George W Bush.
Defenders of the policy say it provides a way of hitting high-profile targets, such as al-Qaida number two, Abu Yahya al-Libi. But critics say the definition of militant is used far too broadly and there are too many civilian casualties.
