KABUL, Afghanistan - Two security incidents within 24 hours involving Afghan government officials have taken some of the glimmer off this month's generally successful presidential election and renewed concerns about safety in Kabul.

Hours after unknown gunmen kidnapped a deputy minister in President Hamid Karzai's government, a police officer engaged in an argument with a female member of parliament opened fire and wounded the lawmaker in the leg, officials said Wednesday.

The lawmaker, Maryam Koofi, was in stable condition at a local hospital, according to a statement from the Afghan Interior Ministry. The police officer was detained and is under investigation, officials said.

The shooting took place around 10 p.m. local time Tuesday near Koofi's home in Arya City, a housing complex normally regarded as one of Kabul's safest. Hashmat Stanikzai, a spokesman for the Kabul police, said the officer fired one or two bullets.

Koofi is a lawmaker from Takhar province, in northern Afghanistan, and is the older sister of the prominent lawmaker and women's rights activist Fawzia Koofi.

Earlier Tuesday, a group of gunmen abducted Ahmad Shah Wahid, the deputy minister of public works, as he was riding in his car on his way to work. The gunmen pulled his car off the road, pulled him into their vehicle and drove off, said Sohail Kakar, a spokesman for the Public Works Ministry.
