An Israeli airstrike after sundown Wednesday killed two militants in northern Gaza, Gaza officials and the Israeli military said.

Hamas security said the two dead belonged to Islamic Jihad. Palestinian health ministry official Moaiya Hassanain said five bystanders were wounded.

The Israeli military said the target was a senior Islamic Jihad militant who was involved in firing rockets at the Israeli city of Ashkelon, north of Gaza.

Palestinian security officials said the two militants jumped out of their car when they heard the Israeli aircraft approaching. The Israeli craft fired a missile at them, killing them.

Since Israel ended its offensive against Gaza militants last month, there has been sporadic violence, including rocket fire from Gaza and Israeli airstrikes. The military said no rockets were fired from Gaza by sundown Wednesday.
