BAGHDAD, Oct. 17 (Xinhua) -- A suicide bomber blew up a truck bomb over a key bridge on the main highway west of Ramada, the capital city of Anbar province, while four soldiers were killed in separate incident near the city of Fallujah, a police source said Saturday.
The suicide bombing destroyed the bridge of Warrar early in the morning in the al-Jazeera area west of Ramadi, some 110 km west of Baghdad, and caused the closure of the highway that links Iraq to the neighboring countries of Syria and Jordan, the source told Xinhua on condition of anonymity.
There were no casualties reported by the blast on the bridge, the source said.
In a separate incident, a roadside bomb went off near an Iraqi Army patrol near the city of Fallujah, some 50 km west of Baghdad, killing four soldiers and wounding 13 others, the source added.
A day earlier, insurgents blew up explosive charges on another bridge near the town of Amriyat al-Fallujah, near the city of Fallujah, destroying the bridge that links Iraq's western province of Anbar to Baghdad and Karbala province.
The attacks came nearly a week after triple explosions ripped through the city of Ramadi, killing 19 people and wounding 81 others.
The once volatile province of Anbar has been relatively calm for more than two years after Sunni tribes and anti-U.S. insurgent groups turned to cooperate with the U.S. troops and Iraqi security forces against al-Qaida in Iraq network.
