华尔街日报也报道了，美国情报机构宣布有high confidence确认是巴勒斯坦伊斯兰圣战队的恐怖分子干的

（至于是不是丧心病狂杀自己人自导自演没说）

美国的判断是基于美国窃听到的恐怖分子通讯和其他分析。

The U.S. has collected “high confidence” signals intelligence showing that the explosion at a Gaza hospital compound on Tuesday was caused by the militant group Palestinian Islamic Jihad, U.S. officials said, buttressing Israel’s contention that it wasn’t responsible for the blast.

The U.S. assessment drew, in part, on communications intercepts and other intelligence gathered by the U.S., defense officials said.

“Our current assessment, based on analysis of overhead imagery, intercepts and open source information, is that Israel is not responsible for the explosion at the hospital in Gaza,” White House National Security Council spokeswoman Adrienne Watson said, adding that the U.S. continues to collect information on the incident.
