Witnesses and residents at the gas explosion in Harlem, New York have told of the confusion around the collapse. One resident said she thought the explosion was "thunder at first".
Another eyewitness at the scene said he saw people "dragging an old lady out of the rubble".
Prime Minister David Cameron visited the Yad Vashem's Holocaust History Museum in Jerusalem where he rekindled the eternal flame in memory of victims of the tragedy.
The frustrations of the families of the passengers on board the missing Flight MH370 boiled over as angry relatives threw bottles at Malaysia Airline officials.
The video, taken in a Beijjing hotel room and posted to a Chinese social media site, appeared to show several water bottles being thrown at representatives as they delivered no new information on the fate of the 239 passengers.
The search for the plane, which disappeared off the radar at 1.30am on Saturday, has so far proved fruitless with aviation experts calling it one of the most baffling mysteries in recent history.
Operations to find the aircraft are now covering 27,000 nautical miles with some 42 ships and 39 aircraft from several countries now involved in the search.
The National Transportation Safety Board wrote on Twitter after the gas explosion in New York:
NTSB sending go-team of investigators to NYC gas explosion.
Olympic gold medallist Jessica Ennis-Hill said she will settle for watching the Commonwealth Games on television as she prepares for motherhood.
The 28-year-old heptathlete will support Team GB from the sofa come July, but admits that she will be rather preoccupied with the arrival of her first child with husband Andy, due the same month.
Ennis-Hill said: "I will be supporting but I will be at home, probably very tired and not knowing what's going on in the world, to be honest.
"I'm sad to be missing it this year but very much looking forward to supporting the team."
The New York City Office of Emergency Management tweeted:
