A rocket landed in a crowd of civilians near Kabul's police headquarters Saturday, and a truck full of rockets smuggled into the city under a pile of hay exploded nearby moments later, officials said. At least five people were killed and 24 wounded, officials said. The truck contained five 107 mm rockets rigged to explode, said Gen. Mohammad Zahir Azimi, the Defense Ministry spokesman. He said two of the rockets detonated but three did not. The sound of the blasts reverberated through Kabul around 8:20 a.m. Moments earlier, a rocket was fired - apparently by remote control - toward the police station, but it instead landed in a crowd of civilians, said Najib Nekzad, a press officer for the Interior Ministry. Nekzad said five civilians were killed. The Health Ministry said 24 people were wounded. The attacker smuggled the rocket launcher and rockets into the city by hiding them under a pile of hay, Nekzad said.
