US President Obama telephones mums on Mother's Day

President Barack Obama marked Mother's Day in the US by calling three mums from the Oval Office.

The three had been selected from letters that they had written to him recently.

Mr Obama told one mum: "You're doing the most important work there is".

The president's own mother, Ann Dunham, died of ovarian cancer in 1995.
