Residents in a town in Cornwall have received a letter from Royal Mail apologising for late mail - explaining that its delivery workers were being hampered by dive-bombing seagulls.

Royal Mail said those living in the affected zone in Liskeard could choose to wait until the birds were not aggressively protecting their young, or nominate a new address.

One Liskeard resident described it as "deadly" to go outside when the birds were nesting.
