Education minister Prof. Georgi Valchev answered MPs' questions today at a session of parliament's education and science committee.

Before that, the committee held a minute's silence for those killed yesterday in two serious pile-up crashes on the Trakia motorway.

Neli Karabahchieva of the Progressive Bulgaria parliamentary group asked the first question. She wanted to know how Bulgarian Sunday schools abroad work.

Krasimir Valchev of GERB-SDS, the committee's deputy chair, asked the minister whether phones could be banned in schools and social media for children.
