SELINSGROVE — A group of young missionaries from central Pennsylvania who had gone to Uganda to help build a wall around a church and school and experience Africa firsthand were rocked by blasts that injured six of them, a pastor said today.

The Rev. Kathleen Kind of the Christ Community Church in Selinsgrove said none of the injuries appeared to be life-threatening, though one missionary suffered serious leg injuries in the explosions Sunday that killed at least 74 people.

"The nature of the trip was to work with our sister congregation in Uganda," said Kind, who added that the missionaries have been in contact with their families. "The community of faith here is actively praying for these persons."

Three of the injured were from her church and the other three were from other churches in the area, she said. They were part of a group of about 14 who had traveled to Uganda for a mission last month and were supposed to have returned today.

Police in Uganda believe an al-Qaida-linked group is behind the blasts. The deadliest attack occurred at a rugby club as people watched the World Cup final between Spain and the Netherlands on a large-screen TV outdoors. The second blast hit at an Ethiopian restaurant.
