GAZA CITY, Gaza Strip (AP) - Witnesses say an Israeli airstrike has hit a high-rise in downtown Gaza City where a number of local and foreign news organizations have offices.

Thick black smoke rose from the building Monday as ambulances rushed to the scene. Paramedics say one person was killed and several wounded.

It's the second strike on the building in two days. The Hamas TV station, Al Aqsa, is located on the top floor.

Israeli aircraft have struck several crowded areas in the Gaza Strip, driving up the Palestinian death toll to 94 and devastating several homes belonging to one clan as Israel broadened its targets in the 6-day-old offensive.

Hamas fighters also have fired hundreds of rockets into Israel in the current round of fighting, including 75 on Monday, one that hit an empty school.

Palestinian militant group Islamic Jihad says the strike killed one of its top militant leaders.

Monday's strike in downtown Gaza City was part of a widening 6-day-old offensive meant to quell Hamas rocket fire.

It's the second strike on the building in two days. The Hamas TV station, Al Aqsa, is located on the top floor.

Islamic Jihad has sent a text message to reporters saying that Ramez Harb was killed in the strike Monday. Harb is a leading figure in their militant wing, the Al Quds Brigades.
