"Your brother has been killed in a martyrdom operation," the caller said, using a common euphemism to describe a suicide bombing.

Israeli sources have characterized it as "the 'most serious' of martyrdom operations."

The complaint says he also said the attack was intended as a "martyrdom operation."

"We have in the past stopped martyrdom operations against the enemy," he said, referring to suicide bombings.

"There will be more martyrdom operations until the occupation is defeated."

On Sunday, three militant groups jointly claimed responsibility for the attack, which they called "a martyrdom operation."

But the other pressure is from his own people, and nearly all the Palestinians support martyrdom operations.

"I consider this type of martyrdom operation as an evidence of God's justice."

"Making peace is more heroic than martyrdom operations," he said.

"Israel is trying its best to talk about how this meeting will lead to a cease-fire or ending the martyrdom operations," he said.
