The attacks escalated in 1947, when more than a dozen writers were called to testify.

But we did learn that the attacks would escalate.

Israel has "rid itself" of Gaza, but anti-Jewish attacks from there have only escalated.

In recent weeks attacks on pensioners like mr bishop have escalated.

The attack escalated into a shoot-out that spilled into the surrounding neighborhood.

In the past weeks, these attacks have escalated from vandalism to attempted murder.

Additionally, several police officers were killed and injured as attacks escalated.

From then on, Al Qaeda's attacks escalated in skill, secrecy and savagery.

In this period the terrorist attacks against Israel (such as the Dolphinarium massacre) escalated.

I wonder if the racist attacks would escalate if someone added an "H" to the wording on all of the police cars.
