Former Prime Minister Gordon Brown has proposed a raft of new safety measures for schools in Pakistan following a series of deadly attacks.
Mr Brown, now a UN envoy for education, met with Pakistani leader Nawaz Sharif recently to discuss the measures.
Mr Brown says he wants to help schools "stand up to terrorist violence" after schools across Pakistan were targeted in more than a thousand attacks - more than anywhere else in the world.
Among Mr Brown's proposals - drawn up in collaboration with the charity World at School - are peace zones around schools, as well as boundary walls, security checkpoints and the deployment of armed guards.
Mr Brown has appealed to the international community to finance the initiatives.
Later this year, the UN envoy is expected to support international proposals to give schools and places of education a protected status during military operations.
