A spokesman for the Taliban is denying the allegations of a freed Canadian hostage who says his wife was raped and his daughter killed by their abductors.

Upon his return to Canada Friday, Joshua Boyle told reporters that during his five years in captivity, held by the Taliban-linked Haqqani network in Afghanistan, his wife's rape was assisted by the captain of the guard and supervised by the commandant of the network.

He said the Haqqani leadership authorized the murder of his daughter in retaliation for his refusal to accept an offer from the kidnappers, but did not elaborate.

However, a spokesman for the terrorist organization, Zabihullah Mujahid, has released a statement saying Caitlan Coleman had a "natural miscarriage" after an illness that couldn't be treated because they were in a remote area with no doctors.

Mujahid claims the statement Boyle gave in Canada was "force fed" to him.

Mujahid also says "from the time the couple were detained until their release" Boyle and Coleman were never separated because the kidnappers "did not want to incite any suspicion."

"No one has either intentionally murdered the child of this couple and neither has anyone violated or defiled them," Mujahid said in the statement, which was posted to the website of the Taliban's media unit. Media have not been available to verify any of the Taliban's claims.

Boyle told The Canadian Press Saturday that conditions during the five-year ordeal changed over time as the family was shuffled among at least three prisons.

He described the first as "remarkably barbaric," the second as more comfortable and the third as a place of violence in which he and his wife were frequently separated and beaten.

A military statement issued Sunday from Pakistan's army said that a roadside bomb near the Afghan border has killed four soldiers, and wounded three others. It said the troops were taking part in a search operation for the militants who had held the American-Canadian family that was rescued last week.

Pakistani security officials said three bombs went off in the attack, which was claimed by the Pakistani Taliban. The officials spoke on condition of anonymity because they were not authorized to brief reporters.
