A Palestinian militant was killed and another was injured in an Israeli military strike in northern Gaza Strip, a medical spokesperson said Monday.

The strike occurred as the militants were firing mortars at several Israeli tanks and bulldozers that entered Palestinian- controlled areas in Beit Hanoun town, where borders Israel.

An hour ahead, four Palestinian militants were wounded in a similar airstrike in the same area, said Ashraf al-Qedra, spokesperson of the Health Ministry in Gaza. He added that one of the injured was in critical conditions while the other three sustained moderate injuries.

Meanwhile, Israeli media reported that the aerial attacks targeted the militants shortly after five rockets were fired from Gaza this morning. The rockets landed in the Sha'ar Hanegev Regional Council in Negev, causing no damage or casualties.

The cross-border violence renews days after Israel killed five Palestinians in a similar wave that lasted for two days. The dead included Hisham al-Saidini, a senior leader of an Al-Qaeda- inspired group Tawhid and Jihad. Israel accused al-Saidini of planning and taking part in attacks against its territories from Gaza and the neighboring Sinai Peninsula.
