West Midlands Police said they were carrying out checks on buses across the region following the transport bombings across London.

The force said high profile patrols were in progress at "prime public locations" as part of emergency plans triggered by the high state of alert put in place by the Chief Constable as a precautionary measure earlier today.

In a statement, West Midlands Police sought to reassure people there was no specific threat to the West Midlands.

It read: "Our message to the public is to remain calm and vigilant. As normal we would ask for the support of the public and ask them to report anything suspicious to us. They are also urged to look after their bags so they won't be mistaken for suspicious packages.

"We will keep the public informed of developments in the region. Public safety is our absolute priority."

The force also sought to reassure members of ethnic minority communities that it would take "robust" action against any reprisal attacks.

The statement said: "West Midlands Police enjoys excellent relations and consultation with all ethnic and cultural groups. We will listen to their concerns and do everything in our power to reassure them.

"We are mindful that communities don't become a target because of the actions of a few. Hate crime will not be tolerated and we will take robust action if required. It is only with the support of all communities that terrorism can be disrupted and defeated."

Train travel in the Midlands has also been severely affected by the explosions. Train services between the West Midlands and London have been suspended in the wake of the explosions on the capital's transport network.

A Network Rail spokesman said south-bound services into the capital were terminating at Watford with no onward bus transfers.

Chiltern Railways services between Birmingham Moor Street and London Marylebone were also suspended.

"The message we are trying to get across to passengers is don't travel if you don't have to," the Network Rail spokesman said.

North-bound services from Watford to Coventry, Birmingham and stations towards Manchester, Liverpool and Glasgow were running as normal, he added.

A Chiltern Railways spokesman added: "It is not clear when services will resume, but in the meantime, people are being advised by the police to avoid all travel to the capital."
