A senior Hizbullah official vowed on Sunday to press ahead with street protests and other peaceful means to topple Lebanon's Western-backed government, but said the group's plans would not be announced beforehand. "There is no specific time frame and no final plans. There is a basket of ideas which we will use the way we see fit for achieving our goals," Sheik Naim Kassem, Hizbullah's deputy secretary-general, told the group's Al-Manar TV station. Hizbullah has warned that the group would hold mass street protests seeking to force the government from power. Those protests were postponed after Tuesday's assassination of Industry Minister Pierre Gemayel, an anti-Syrian Christian leader.
