Schoolchildren have been shut indoors during the hottest day of the year because of menacing seagulls.

Ysgol Eifion Wyn in Porthmadog, Wales has been forced to keep children off the playground during break-time at least twice this week as herring gulls have been swooping around the heads of parents, teachers and kids.

The divebombing seagulls have left the school in "lockdown", in fear of their sharp beaks.

The situation is so dire that some parents have reported being "too scared" to pick up their children.

Seagulls nest on the roof of the school, and swoop down on anyone who dares venture outside.

It is believed their aggressive behaviour is aimed at protecting their chicks.
