An Israeli air strike on the Gaza Strip before dawn Sunday has hit two Palestinian militants, killing one and wounding the other.

An Israeli military statement said its aircraft targeted a rocket-launching site where militants were preparing to fire a rocket into southern Israel.

Later Sunday, Israeli officials said rockets were fired from the Gaza Strip into southern Israel without causing any casualties.

The incidents followed a three-day lull between the two sides, bringing some respite from a recent upsurge in cross-border fighting.
