BAGHDAD (AP) — Multiple explosions rocked Baghdad on Wednesday, killing at least 34 people and sending plumes of smoke into the sky across the street from a major government building in a brazen reminder of the ability of insurgents to penetrate the heart of the capital.

The attacks come as al-Qaida-led militants are battling for control of mainly Sunni areas to the west in the first test of the Shiite-led government to maintain security in the country more than two years after the withdrawal of U.S. troops.
