a suicide bomb attack at Kabul police headquarters in Afghanistan

One person was killed and six injured Sunday when an
explosion rocked Kabul's police headquarters in the centre of the
capital, sources said, according to dpa.
"Colonel Mohammad Yasin, manager for Kabul police chief's office, was
killed and six people were wounded in this morning's attack," a
police officer said.
"We have received six injured people in the nearby hospital," said
Kaneshka Nooristani, spokesman for the Public Health Ministry.
The explosion occurred on the third floor next to the police chief's
office, but it was not immediately clear if it was from a hidden bomb
or a suicide attacker.
Another officer said that Kabul police chief was the main target,
"but he is fine."
