An Israeli air strike destroyed the office of Palestinian Foreign Minister Mahmoud al-Zahar on Thursday in an attack that signaled Israel would pursue its Gaza offensive while fighting along a second front in Lebanon. No one was hurt in the night-time raid on the Foreign Ministry building in Gaza City, Palestinian security officials said. Israel killed at least 24 Palestinians in the Gaza Strip on Wednesday, including nine members of one family in an air strike that destroyed a house where the army said senior Hamas commanders were meeting. "This is state terrorism against the Palestinian people," Foreign Ministry spokesman Taher al-Nunu said about the latest attack. An Israeli military spokeswoman in Tel Aviv confirmed the air strike and said the ministry was used by the governing Hamas group to further the movement's activities.
