In the first attack, a car full of explosives detonated around midday near Kabul's 6th district police compound, according to Basir Mojahid, a spokesman for the city's police chief. Most of the injured were civilians.

Two insurgents targeted the police compound, while two others entered the nearby police academy, police said.

After a six-hour standoff with Afghan security forces, all four insurgents were killed, Mojahid said.

In the second attack, two gunmen targeted the Afghan intelligence agency Wednesday afternoon, the police spokesman said. The gunmen were killed before reaching the building, police said.
