Heavy snow has again caused travel problems and lead to the closure of hundreds of schools in the West Midlands.

It also forced the runway to close at Birmingham International Airport.  A spokeswoman said: "The airport remains open and as always, the advice to passengers is to check with their airlines."

The closure has so far caused the cancellation of seven outbound flights and two scheduled arrivals have been diverted to land elsewhere.

Thousands of pupils in Birmingham have been told to stay at home, as about a quarter of the city's schools were closed.

On Tuesday, Birmingham City Council closed every school in the city under the Emergency Closure of Schools Notice, attracting criticism from many parents who called it a "bad example" to children.

On Thursday the decision was left to individual head teachers, a council spokeswoman said. So far 111 schools from a total of 428 have announced closures.

A spokeswoman for Herefordshire Council said 42 schools would not open, adding: "Gritting teams have been out gritting all main roads and secondary routes this morning and they are doing all they can to keep the county moving in today's snowy conditions.

"Focus has also been placed on areas of steep gradients and those subjected to heavy snowfall but many side roads are potentially dangerous to drive down."

A spokesman for the Central Motorway Police Group, based in Birmingham, urged motorists to drive "with common sense".

Heavy snowfall in central Birmingham has closed one lane on the A38 Aston Expressway, a busy main route into the city centre leading from the M6 motorway and the north of Birmingham.
