Answer 1

For a single record in array:

db.getCollection('documents').update(
    { },
    {'$pull':{ 'items':{'mobile': 1234567890 }}},
    {new:true}
);

For a multiple records with same mobile number in array:

db.getCollection('documents').update(
    { },
    {'$pull':{ 'items':{'mobile': 1234567890 }}},
    {new:true,multi:true}
)
