Two British nationals are believed to have been killed in a US drone attack in Pakistan, family and friends of the men said Friday.
Terror suspects Ibrahim Adam and Mohammed Azmir are thought to have died in a CIA missile strike on Waziristan, a remote and lawless mountainous region along the border with Afghanistan.
Adam’s father confirmed that his son was killed by an American unmanned aircraft.
A close friend of Azmir’s family, who did not want to be named, said: “They have taken it very badly – this is the second son who has been killed in a drone strike.”
It is not known precisely when the men died, but it is thought to have been at least three months ago, according to a source with personal connections in Pakistan.
Adam, 24, from east London, had been on the run from the UK authorities since absconding from a control order in May 2007.
His brother, Anthony Garcia, was jailed for life in April 2007 for his part in a major fertiliser bomb plot to attack targets in London and across the UK.
Adam was made subject to a control order after being stopped while en route to Syria after the British authorities claimed he was planning to travel to Iraq or Afghanistan for jihadist training or to fight Western forces.
Father-of-three Azmir, 37, who lived in Ilford, Essex, outside London, was made subject to a Treasury order freezing his assets in February 2010 in response to concerns he was involved in funding terrorism.
He is not currently on the Treasury’s list of people and organisations subject to financial sanctions.
It is believed that Azmir’s brother, Abdul Jabbar, 32, was killed in an earlier CIA unmanned drone attack in Pakistan in September last year.
The Foreign Office could not confirm Adam and Azmir’s deaths but said it was investigating the reports.
A spokesman said: “We are aware of reports and are looking into them further.”
The Home Office declined to comment.
The CIA’s drone programme in Pakistan, which is not publicly acknowledged by the US, is hugely controversial.
The Pakistani authorities have criticised the attacks as violations of their country’s sovereignty and international human rights campaigners have condemned reports of innocent civilian casualties.
American officials have privately said that the strikes have killed many Taliban and Al Qaeda commanders.
