IRBIL, Iraq (AP) — Thousands of Kurds and supporters took to the streets in northern Iraq Thursday to protest the Turkish parliament's decision to authorize the government to send troops across the border to root out Kurdish rebels who have been conducting raids into Turkey.

Elsewhere, U.S. forces detained 15 suspected militants in raids, while an insurgent threw a hand grenade into a school in the south, wounding six boys.

The vote in Turkey on Wednesday removed the last legal obstacle to an offensive, but there was no sign of imminent action as the United States and the Iraqi government urged restraint.
