CORVALLIS, Ore. -- The community of Corvallis is coming together once again nearly three months after an alleged arson attack at one of the city's mosques.

Religious and city leaders were joined by many others for the ceremonial planting of a tree that, they hope, symbolizes a community on the mend.

In a sign of unity, the same people who helped get the mosque back on its feet after the fire, gathered outside the Salman Alfarisi Islamic Center. They planted a tree, rooting the towns commitment to peace.

Crowds gathered outside the Islamic Center in Corvallis to not only plant a "peace tree," but to also honor those who helped restore this Muslim place of worship after an alleged arson attack in late November.

The city's mayor, along with several other religious leaders in the community, commemorated the event. Once they finished speaking, the group planted an evergreen where everyone had a hand in scooping dirt over the tree's roots.

"I hope, by planting this tree, people will plant love, respect, understanding, kindness toward each other, so we can all live in peace and harmony," said Mohamed Siala, Salman Alfarisi Islamic Center.

The tree is a Mountain Hemlock, which, organizers say, was handpicked by members of the Islamic Center and various community members. It is a species indigenous to Oregon.

Meanwhile, the arson investigation at the Islamic Center continues. The FBI is looking into whether the arson could have been retaliation after a suspect, who sometimes worshipped at the mosque, was arrested for plotting to bomb a Portland Christmas tree lighting. Nineteen-year-old Mohamed Mohamud remains behind bars in that case.
