Following the decision by the European Union to call for a day of mourning today in light of the tragic events in the United States, Europe's stock exchanges are to observe three minutes' silence from 11am BST.
The London Stock Exchange has asked member firms to refrain from trading during this time and automatic execution will be suspended. Deutsche Börse and Eurex have also confirmed that trading on Xetra in shares of the indices DAX and MDAX as well as in Neuer Markt shares will be halted for the minutes of mourning.
