Five killed in Gaza blast

Five men have been killed in an explosion at a militant training camp in the southern Gaza Strip, a Palestinian medical official said.

Gaza Health Ministry spokesman Adham Abu Salmia said the blast happened inside a training site for militants from the Islamic Jihad group. He said 11 other men were injured in the blast.

The Israeli military said it carried out an air strike against the militants but would not elaborate.

Islamic Jihad is one of Gaza’s militant groups which frequently fires rockets into southern Israel, prompting Israeli reprisal strikes.

The group said one of its field commanders was killed and vowed revenge in a text message sent to reporters.
