“The explosion targeted a US patrol passing through the area,” an Iraqi journalist in Mosul, Mahir al-Zanun, told Aljazeera on Friday.
Witnesses told al-Zanun a number of US soldiers from the targeted patrol were killed in the explosion, but a US military spokesman said the explosion did not leave American casualties.
Reporting from the scene, al-Zanun said US forces had sealed off the area to investigate the blast.
“The explosion also damaged nearby buildings and cars,” he added.

Oil exports from the southern terminals at Basra and Khor al-Amaya were running at about 1.5 million barrels (bpd) a day, compared to 1.6 million bpd on Thursday and 2.0 million earlier in the week.
It was unclear whether the fall was due to the attack on Friday or to normal fluctuation in flow rates, shipping agents said.
Fighters on Thursday attacked eight pipelines linking a southern oilfield to a pumping station near Basra.
There were no indications that exports, which have proceeded sporadically this month, had resumed on Friday morning, but sources said they could restart at any moment to top off tanks.
