An upcoming edition of its al-Qaeda’s English-language terror magazine, INSPIRE is headlining “Train Derail Operations,” where they spell out ways to create rail disasters in a transportation system that lacks the stiff security procedures of airline travel.

Washington Times It’s competing Sunni extremists group, the Islamic State, for more than a year has advocated using vehicles to mow down innocents with cars and trucks. Its murderous followers have weaponized vehicles in Nice, Berlin and London, creating hundred of deaths and injuries.

Adding trains to the terrorist’s priority list would put at risk virtually every mode of transportation and placed added pressure on the U.S. Department of Homeland Security.

The Middle East Media Research Institute (MEMRI) put out a report on Friday saying al-Qaeda has teased the Inspire articles with a trailer appearing on Telegram app channels operated by its fans.

“The trailer highlights that derailments are simple to design using easily available materials, that such a planned attack can be hard to detect, and that the outcome can substantially damage a country’s transportation sector and the Western economy in general,” MEMRI said.

The U.S. maintains over 100,000 miles of rail. But the trailer features scenes of just one system, the subway. Its shows cars flashing through urban tunnels. It quotes from U.S. Government Accountability Office reports on the vulnerability of rail lines to sabotage. It then shows what appear to be rudimentary devices that can be clamped onto a line to cause a derailment.

“Simple to design,” the promo says in English script, mentioning “America” several times. “Made from readily available materials. Hard to be detached. Cause great destruction to the Western economy and transportation sector.”

Al-qaeda in recent months has depicted itself as making a comeback from its headquarters in Yemen. It has created new alliances in North Africa, is using social media to attract adherence and has not given up the idea of another mass-casualty attack such as its commandeered airliner strike on New York and the Pentagon in 2001.

Osama bin-Laden’s son, Hamza, steps into his father’s sandals as al-Qaeda tries to make a comeback.

Washington Post The voice is that of a soft-spoken 28-year-old, but the message is vintage Osama bin Laden, giving orders to kill. When the audio recording began turning up on jihadist websites two weeks ago, it was as if the dead terrorist was channeling himself through his favorite son.

“Prepare diligently to inflict crippling losses on those who have disbelieved,” Hamza bin Laden, scion of the Sept. 11, 2001, mastermind, says in a thin baritone that eerily echoes his father. “Follow in the footsteps of martyrdom-seekers before you.”

The recording, first aired May 13, is one in a string of recent pronouncements by the man who many terrorism experts regard as the crown prince of al-Qaeda’s global network. Posted just two weeks before Monday’s suicide bombing in Manchester, England, the message includes a specific call for attacks on European and North American cities to avenge the deaths of Syrian children killed in airstrikes.
