Children hurt in attack on Afghan schools

There was no claim of responsibility for the attack, which coincided with the start of a meeting in Pakistan aimed at getting a stalled peace process with the Taliban back on track. 

Khost, on the border with Pakistan, has been relatively calm in recent months but last year dozens of people were killed in two suicide bomb attacks in April and July.

On Monday, officials from Afghanistan, Pakistan, China and the United States met in Islamabad in a bid to restart a peace process that broke down in July when news was announced that Taliban leader Mullah Mohammad Omar had died two years earlier. 

Pakistan on Monday said that no precondition should be attached for talks between the Afghan government and the Taliban.
