The service at Royston Primary remembered Paul and Jay Ross
Candles have been lit at a school memorial service for two young brothers found murdered in a car in Lennoxtown.
Pupils, staff and teachers took part in the tribute at Royston Primary, Glasgow, which was attended by Paul Ross.
The six-year-old and his brother Jay, two, were found dead in a car in the Campsie hills on Saturday afternoon.
A man believed to be the children's father, Ashok Kalyanjee, is under police guard in hospital.
BBC Scotland understands that both boys had been stabbed.
Police have still to confirm how the children, who lived in Royston, died.
Members of the Ross family were at the service on Thursday, but the boys' mother did not attend.
The memorial was led by the former school chaplain Rev Russell McLarty.
Pupils sat around a circle of candles, while teachers lit two large candles in memory of the brothers.
They sang hymns and heard clarsach music played by a student from the Royal Scottish Academy of Music and Drama.
Afterwards Mr McLarty said: "The assembly was very much for the children who are coming back to school with all their feelings and the staff too.
"This is a very, very close school and a loving school with a lovely atmosphere.
"It's important to realise that the children are very deep in their thoughts and with the music and the candles and songs that we sang that really helps the children and staff express some of their feelings.
"It gives every single child a sense that they are involved."
When the service finished, the 138 pupils went into the playground where a pear tree was planted in memory of Paul.
Pupils then tied on to a fence blue and yellow ribbons on which they had written their name and a special message.
One message read: "You were a super friend" while another said: "To Paul and Jay we will never forget you."
Pupils returned to the school on Wednesday following the bank holiday weekend and Mr McLarty said they were struggling to return to normality.
He said: "Some children will openly show their tears, others will be much quieter and deeper.
"The teachers at this school are very committed and know the children's parents, and I know that the head teacher has known Paul's family all the time she has been here, so obviously it is a very deep sense of grief and loss."
