Israeli warplanes have pounded smuggling tunnels under the Gaza-Egypt border after a Palestinian bomb killed an Israeli soldier.
The border flare-up came 10 days into an informal ceasefire.
It also came just hours before President Barack Obama's new Mideast envoy, George Mitchell, was due to meet Israeli leaders.
The military said the soldier was killed yesterday on Israel's frontier with the Gaza Strip by a roadside bomb planted on the Gaza side.
Israel sent tanks and bulldozers into northern Gaza to plough up the attack site and launched an airstrike that wounded a Hamas militant.
Meanwhile, residents said two Israeli air strikes early today targeted smuggling tunnels under the Gaza-Egypt border. They said the strikes sent hundreds of people fleeing.Reuse content
