Amid a resurgence of post-election and post-New Year violence, U.S. soldiers in Iraq reported the capture of at least 11 suspected insurgents and the seizure of four weapons caches, officials said Thursday.

Soldiers of the 101st Airborne Division’s 1st Brigade Combat Team made the arrest and discoveries in several cities around Tikrit.

In the first incident, the soldiers — part of Task Force Band of Brothers — were on patrol near Hawijah when they came upon a suspicious truck.

Three men ran from the truck, which had stopped at the side of a road, and another five men were in the back. The soldiers found rocket-propelled grenades and launchers, machine guns and bomb-making components in the truck. The soldiers arrested all eight men from the vehicle.

Three other men were detained in a separate incident near Hawijah when their vehicle was stopped and was discovered to have 30 pistols inside, far exceeding the amount of personal weapons Iraqis are allowed to carry.

Near Beiji, soldiers of the 101st were given a tip by a local man that a weapons cache was buried nearby. The soldiers found more than 6,000 anti-aircraft artillery rounds, which were taken to a nearby base for disposal.

A fourth cache, containing 25 artillery rounds likely destined for use as roadside bombs, was discovered near Kirkuk, officials said.
