GAZA, Sept 27 (Reuters) - An Israeli strike in the central Gaza Strip on Monday killed three gunmen belonging to the Islamic Jihad group, Palestinian medics said.

The Israeli military had no immediate comment. Israel often carries out strikes against militant targets in Gaza, which is controlled by the Islamist group Hamas.

Medics said they had recovered three bodies from the site of an explosion that occurred after darkness fell outside Bureij refugee camp, near the Israel-Gaza frontier.

Hamas television reports said the blast had been caused either by an Israeli air strike or cross-border tank fire. (Reporting by Nidal al-Mughrabi; Writing by Allyn Fisher-Ilan; Editing by Kevin Liffey)
