Gunmen ambushed an Iraqi police convoy north of Baghdad today, killing 28 policemen, including the commander, and wounding 25 more, police said.
At least 95 US soldiers have died in Iraq in October
It was the second major ambush of police in the Baquba area in the past week -- on Sunday, an assault on a convoy of buses near Baquba killed 13 Iraqi police recruits.
The campaign against Iraqi security forces highlights the challenge the Iraqi government faces in establishing an independent and powerful police force and army capable of taking over security from U.S. troops in violent areas.
The latest attack targeted police in a volatile town near Baquba, 65 km (40 miles) north of Baghdad, an area with a mixed population of Shia and Sunni Arabs that has seen relentless sectarian bloodshed.
Insurgents frequently attack Iraq's US-trained security forces, which are a key part of Washington's plans for an eventual withdrawal of its 140,000 troops in Iraq.
Earlier today, gunmen attacked a station for an Iraqi special police force in another town near Baquba, killing six police and wounding 10, police said.
Baquba is a stronghold of Sunni insurgents battling US forces and the Shia-led government.
On Sunday, a bomb blast and an ambush on a convoy of buses near Baquba killed 13 Iraqi police recruits. Several more recruits were kidnapped. Another 25 police recruits were wounded in that attack.
