BAGHDAD — An Iraqi Parliament member who was also the leader of a local council of the Sunni Awakening, a US-backed group of Sunni militias that switched sides to fight against Al Qaeda in Iraq, was killed in a suicide bomb attack in Anbar Province Tuesday, security and government officials said.

The lawmaker, Efan al-Essawi, who owned a construction company, had gone to inspect a road that it was building to connect Fallujah with the main highway in Anbar, a trade route that leads west to Syria and Jordan. The region has been embroiled in turmoil since last month, when protests, led mostly by Sunnis, broke out against the Shi’ite-led government of Prime Minister Nouri al-Maliki. The demonstrations continued in Anbar on Tuesday.
