At least seven rockets fired by Palestinian militants in the Gaza Strip struck southern Israel, a day after Israel's prime minister warned that ending the rocket fire could take a long time. VOA's Jim Teeple reports from our Jerusalem bureau.

Hamas militants are keeping up their rocket attacks, despite threats of massive retaliation from Israeli officials and a plea by moderate Palestinian President Mahmoud Abbas to renew a ceasefire with Israel that collapsed more than a week ago.

Miri Eisen a spokeswoman for Israeli Prime Minister Ehud Olmert will not say if Hamas leaders will be targeted by Israeli forces, but she says those who are firing rockets at Israel will pay a heavy price.

Hamas leaders have warned Israel not to target their leaders, and have also threatened to kill an Israeli soldier being held by Palestinian militants in Gaza.

Hamas has for the time being also rejected a call by Palestinian President Mahmoud Abbas to agree to a one-month cease-fire with Israel. Hamas leaders say they will only accept a cease-fire if Israel agrees to extend it to include the West Bank, something Israel rejects.
