Travellers are not being allwed to take hand luggage onto planes.

Security at all airports in the UK was stepped up after police made arrests following an anti-terrorist operation lasting several months.

The threat level has been raised to critical - the highest possible.

All airports have asked travellers to allow extra time to check-in and expect to face delays.

The Department for Transport said passengers will not be allowed to take any hand luggage on to any flights in the UK.

Only the barest essentials - including passports and wallets - will be allowed to be carried on board in transparent plastic bags, the department said.
