The Taliban has agreed to begin substantive talks with the Republic team in Doha in the coming days, according to sources close to the group, which would end the peace process stalemate. 

The sources said that the group plans to attend the Istanbul summit, but wants the end negotiations to take place in Doha. 

Families of the victims of the deadly blasts on May 8 near Sayed al-Shuhada school in the west of Kabul that killed over 80 people--all students--said the incident requires an extensive probe by the United Nations and called for a proper security plan for students in that part of the city. Students have been attacked in that area at least three times recently.

The families appeared at a press conference in Kabul on Sunday where they called for proper attention to be paid to those affected by the incident.
