Tuesday night President Obama flew into Afghanistan after dark for an unannounced visit to the country.
Once in the Afghan capital, Kabul, he and Afghan President Hamid Karzai signed a new agreement that governs future relations between the US and Afghanistan.
The agreement commits the US to a role in Afghanistan's future beyond the 2014 withdrawal date of most US troops.
Hours after President Obama left Afghanistan, at least seven people were killed in a suicide bomb attack in Kabul. The Taliban claimed responsibility for the attack.
Marco Werman talks with Sultana Parvanta, a Kabul resident and a consultant on economic development and women's issues, about her reaction to President Obama's visit to Afghanistan last night.
