Queen's 8 grandchildren hold silent vigil beside her coffin

All eight of Queen Elizabeth II's grandchildren stood in silent vigil beside her coffin Saturday, capping another huge day in which thousands came to pay their respects. Mourners huddled in a line that snaked across London, enduring the city's coldest night in months and waits that stretched up to 16 hours.

Authorities warned that more chilly weather was expected Saturday night. “Tonight’s forecast is cold. Warm clothing is recommended,” the ministry in charge of the line tweeted.
