Manchester blast timed to 2013 UK terror attack: Trump's Deputy Assistant

U.S. President Donald Trump's Deputy Assistant Sebastian Gorka has suggested that the deadly blast at Manchester arena could be timed with the date of another fatal attack in the U.K. four years ago.

Gorka tweeted, "Manchester explosion happens on 4th anniversary of the public murder of Fusilier Lee Rigby. Dates matter to Jihadi terrorists."

Rigby, 25, was the British Army soldier stabbed and hacked to death in London on May 22, 2013 by two Islamists, Michael Adebolajo and Michael Adebowale, who ran over him with a car before attacking him with knives and a cleaver, attempting to behead him.

At least 19 people were killed and 50 injured after what is being investigated as a suspected suicide bombing of a crowded pop concert in Manchester late Monday night.

Last England saw such a deadly terror attack was in 2005 when on July 7, which killed 52 people after terrorists carried out a series of coordinated suicide bomb attacks in central London targeting civilians using the public transport system during the rush hour.

Meanwhile, confirming the details of the attack, Chief Constable of Greater Manchester Police Ian Hopkins said the investigation to identify the perpetrators behind the deadly attack is underway, until which the attack is being treated as a terrorist incident.

"We are working closely with the National Counter Terrorism Policing Network and U.K. Intelligence partners. It is recommended that citizens of Manchester remain away from the area and be vigilant at all times. We are doing all that we can," he said.
