Russian airplane 'broke up in the air'

Too early to draw conclusions about cause, official says

A Russian airliner that crashed in Egypt broke up in the air, an investigator said on Sunday, as the bodies of many of the 224 people killed on board were flown home.

Egyptian President Abdel Fattah al-Sisi urged patience to determine the cause of Saturday's crash, after the Islamic State jihadist group claimed it brought down the A321 in Egypt's restive Sinai Peninsula.
