Liberia's information minister says that a plane carrying an official delegation from Guinea to attend Liberia's Armed Forces Day celebration in the capital has crashed.

Lewis Brown said Monday that the plane went down in Charlesville, near Liberia's largest airport, some 45 kilometers (28 miles) south of Monrovia, the capital. He said there were about 10 people in the delegation but he could not confirm deaths or survivals. Brown said he didn't have further details.

Liberia's President Ellen Johnson Sirleaf confirmed the crash while speaking at a ceremony. She called for a moment of silence for those involved in the crash and declared Tuesday a day of mourning.
