International Development Secretary Justine Greening has condemned as "brutal and senseless" the attack on the US embassy in Libya on 12 September, in which the US Ambassador and three other officials were killed.
She made the statement at the start of the quarterly statement on Afghanistan to the Commons on 13 September 2012.
Ms Greening went on to announce that the transition of security responsibilities from Nato troops to Afghan forces remained on track. Nato combat troops are due to be withdrawn from Afghanistan by 2014.
Despite concerns about the number of attacks by members of Afghan security forces on Nato troops - so-called "green on blue" attacks - Ms Greening said that the vast majority of partnerships between Nato troops and Afghan security were forces were positive.
Partnerships on security and in delivering a functioning civil society remained crucial, Ms Greening said.
Tax revenue collection by the Afghan government had increased by 23% year on year, so decreasing the country's future dependence on international aid.
Ms Greening said that DFID would continue to provide advisers to the Afghan government to increase transparency and eliminate corruption.
In response to questions on the position of women in Afghanistan, Ms Greening said that while the situation had improved, "no-one should be under any illusion that there is a long way to go".
