SANAA, Yemen (AP) — Al-Qaida in Yemen has claimed responsibility for the killing of American teacher Joel Shrum.

Thursday's statement, which was posted on a militant website, accuses the 29-year-old native of Mount Joy, Pennsylvania, of proselytizing in the mainly Muslim Arab nation.

Shrum, who was gunned down on Sunday, had been living in the central city of Taiz with his wife and two sons. He was learning Arabic and teaching English at a language institute.
