Apparent insider attack kills 2 US troops, 3 Afghan police - officials

The attacker in the eastern Afghan province of Wardak was
wearing an Afghan police uniform. He opened fire inside a police
station while US forces were visiting.
Monday’s shooting is the latest in a series of ‘green-on-blue’
attacks, in which assailants are dressed in police or army
uniform.
The incident comes days after a suicide bomber on a bicycle
detonated an explosion outside the Afghan Defense Ministry, killing
nine Afghan civilians and wounding 14 others. On the same day a
suicide bomber blew himself up in the eastern Afghan city of Khost,
leaving eight children and one police officer dead. The attacks
coincided with US Defense Secretary Chuck Hagel`s visit to the
capital.
The end of February saw a surge of Taliban attacks with dozens
civilians killed. On February 24 Afghan police foiled an attack on
a Kabul's diplomatic enclave, killing a would-be suicide bomber. On
the same day two suicide bomb attacks killed two intelligence
agents and a policeman.
