11:15 a.m. Eastern: Islamic State reportedly called for vehicle, knife attacks on civilians

The U.K.'s Telegraph newspaper reported that an Islamic State outlet called on jihadists to use vehicles and knives to attack civilians hours before the London terror attacks Saturday night.

According to the Telegraph, a message was sent out via an encrypted app encouraging jihadists to "kill the civilians of the Crusaders" and to "run over them by vehicles." The message suggested that attacks be carried out during Ramadan, which runs through June 24. 

The Islamic State had called for an "all-out war" on the West during the holy month, which began on May 26, but no group has yet claimed responsibility for Saturday's attack.
