The last major wave of attacks was on May 18.
At least 22 people have been killed in the wave of attacks during the past 18 months.
"Another two or three attack waves, and death will begin to rain down."
Under the plan, a second wave of attacks would follow.
The charge might be almost gone, but perhaps enough remained to take care of the first attack wave.
Three waves of attacks were carried out during the day.
The new wave of attacks is likely to be on economic targets.
In March 2004, another wave of attacks shook the country.
But this wave of attacks comes at a particularly tense time.
The first wave of attacks began on Dec. 22 last year, the police said.
