CHICAGO, IL - JUNE 02: A sign directs travelers to a security checkpoint staffed by Transportation Security Administration (TSA) workers at O'Hare Airport on June 2, 2015 in Chicago, Illinois. The Department of Homeland Security said that the acting head of the TSA would be replaced following a report that airport screeners failed to detect explosives and weapons in nearly all of the tests that an undercover team conducted at airports around the country.

U.S. cities boost security for busy travel week
A man from Lancashire who encouraged Islamic extremists to wage jihad in the West, including targeting Prince George and injecting poison in to supermarket ice-cream, has been convicted today (31 May).
Husnain Rashid, 32, posted messages online glorifying successful terrorist atrocities committed by others while encouraging and inciting his readers to plan and commit attacks.
One of his posts included a photograph of Prince George, along with the address of his school, a black silhouette of a jihad fighter and the message ìeven the royal family will not be left aloneî.
His common theme was that attacks could be carried out by one individual acting alone. Rashid suggested perpetrators had the option of using poisons, vehicles, weapons, bombs, chemicals or knives. Rashid uploaded terrorist material to an online library he created with the goal of helping others plan an attack.
He also planned to travel to Turkey and Syria with the intention of fighting in Daesh-controlled territories. He contacted individuals he believed to be in Daesh territory, seeking advice on how to reach Syria and how to obtain the required authorisation necessary to join a fighting group.
Rashid provided one individual who had travelled to Syria and was known online as ìRepunzelî, with information about methods of shooting down aircraft and jamming missile systems.
All the offences relate to Rashidís activities online between October 2016 and his arrest in November 2017.
Rashidís trial started on 23 May at Woolwich Crown Court but he changed his plea to guilty on four counts on 31 May. He will be sentenced on 28 June.
Sue Hemming from the CPS said: ìHusnain Rashid is an extremist who not only sought to encourage others to commit attacks on targets in the West but was planning to travel aboard so he could fight himself.
ìHe tried to argue that he had not done anything illegal but with the overwhelming weight of evidence against him he changed his plea to guilty.

Story highlights

The State Department has issued a worldwide travel alert warning Americans of terror attacks

State warned of terror groups' plots as well as individuals carrying out their own attacks

(CNN) —  

The United States issued a worldwide travel alert for Americans amid concerns that terror groups and individuals plan more attacks after the Paris massacres.

The State Department warned that groups like ISIS, al-Qaeda and Boko Haram “continue to plan terrorist attacks in multiple regions.”

It also warned of the possibility of individuals carrying out their own attacks.

“These attacks may employ a wide variety of tactics, using conventional and non-conventional weapons and targeting both official and private interests,” the department said in issuing a travel alert that expires on February 24, 2016.

The alert does not instruct Americans to avoid travel, but it does urge U.S. citizens to “exercise vigilance when in public places or using transportation.”

“Be aware of immediate surroundings and avoid large crowds or crowded places. Exercise particular caution during the holiday season and at holiday festivals or events,” the State Department said in the alert.

What to do in a terror attack

The department said that terrorist attacks remain likely as ISIS members return from Iraq and Syria.

It warned that “there is a continuing threat from unaffiliated persons planning attacks inspired by major terrorist organizations but conducted on an individual basis,” pointing specifically to large sporting events, theaters, open markets and airlines.

In July, the State Department issued a “Worldwide Caution” that also warned ISIS and others continued to plan terrorist attacks against the United States and Western interests in Europe.

An “Alert” is time-limited, often for 90 days, at which it can be reviewed. An alert is not necessarily stronger or weaker than a caution. The most recent worldwide travel alert was issued in December 2014, and prior to that in August 2013, September 2011, and May 2011.
