A row has broken out between Germany and Turkey over what German politicians say is an attempt to ban Christmas.

The row centres on an elite school in Istanbul partly funded by Germany, where Turkish authorities have forbidden teachers and pupils from singing carols or celebrating Christmas in any way.

The Istanbul Lisesi usually marks the season with German traditions, but this year Christmas cookies and Advent calendars have been banned at the school.

German teachers recieved an email from the headmaster earlier this month informing them of the new rules.
