GAZA CITY, Gaza Strip — Palestinian officials say a militant riding a motorcycle was killed in an Israeli airstrike Tuesday, and five Hamas officers were injured in a second attack that hit a police car a few hours later in Gaza.

Gaza Health Ministry official Dr. Moaiya Hassanain said the militant was killed and another two injured in the explosion when a rocket hit his motorcycle Tuesday evening.

Such Israeli air attacks have been relatively rare since the end of a three-week Israeli war against Gaza militants three years ago.

The Islamic Jihad, a violent Palestinian group that frequently fires rockets and mortars at Israel, said the he was a former member. The Israeli military said in a statement it targeted a "terror squad" without elaborating.

It said the military will "not tolerate any attempt to harm Israeli civilians and soldiers, and will operate against anyone who uses terror against Israel."

Another airstrike wounded five Hamas police officers later Tuesday, the Gaza health official said. The Israeli military had no immediate comment.

In recent weeks, the militant Islamic Hamas and its West Bank rival, Fatah, have reported progress in efforts to end their rift and reunite Palestinian government. Israel has warned that it would not deal with any Palestinian government that includes Hamas representatives.

Also Tuesday, a hard-line Israeli group said it was launching plans for a new tourist center at the site of a politically sensitive archaeological dig in a largely Arab neighborhood outside Jerusalem's Old City, drawing fire from Palestinian officials.

The project's sponsor, the Elad Foundation, said the new visitors center and parking garage will be built above a section of the excavation area known as the City of David, leaving the ruins below accessible. Construction, which must pass several zoning committees, was still several years away.

Israeli archaeologists at the City of David, named for the biblical monarch thought to have ruled from the spot 3,000 years ago, are investigating the oldest part of Jerusalem.

The site is just outside the Old City walls at the edge of the neighborhood of Silwan in east Jerusalem, the part of the city the Palestinian Authority says it wants as the capital of a hoped-for state.

Israeli construction in east Jerusalem is regularly subject to international criticism. Critics say the new plan will cement Israel's hold on Silwan and could destabilize the volatile neighborhood, where Palestinian residents clash on occasion with Jewish residents and police.
