(Adds army reaction)

HEBRON, West Bank, June 27 (Reuters) - Israeli forces killed a Palestinian teenager during a raid into the occupied West Bank on Friday, local residents and medical workers said.

The residents said the 17-year-old was killed while confronting Israeli troops who raided the village of Beit Umar, near the West Bank city of Hebron.

An Israeli army spokesman said troops fired at a group of militants who hurled firebombs at them, hitting one.

The incident could further disrupt a shaky ceasefire agreement between the Jewish state and Palestinian militant groups in the Gaza Strip. (Reporting by Haitham Tamimi; Writing by Avida Landau; Editing by Stephen Weeks) (Avida Landau: +972-50-936-9478)
