Trump calls Strait of Hormuz 'something that we don't need'

In light of reports that say the U.S. Department of Defense’s preliminary findings have determined the U.S. is responsible for the strike on the Iranian girls’ school that local officials say killed 168 people, President Donald Trump denied knowledge of such findings.

"I don't know about it," the president said to reporters Wednesday, when asked about the reports, as he departed the White House. Right before the president answered, press secretary Karoline Leavitt -- who was standing next to him -- shook her head and appeared to whisper, "no."

Trump also did not acknowledge a question as to whether he’d take responsibility as commander-in-chief.

Earlier Wednesday, the White House did not comment on the report’s alleged findings, insisting that the investigation remains ongoing and that there are "no conclusions" at this time.

A pro-Iran hacking group has claimed responsibility for a cyber attack on Stryker, a U.S. medical technology company, according to SITE Intel.

The hackers, a group called Handala, allegedly deleted company data from over 200,000 systems, servers, mobile devices, and extracted 50 terabytes of "critical data," SITE Intel said.

Handala said the hack was motivated by the U.S. airstrike that struck an Iranian girls' school in Minab as motivation for the cyberattack, SITE Intel said.

Handala has claimed similar breaches amid the Iran war, including against a Saudi oil and gas company, an Israeli insurance company and the Israel Defense Forces.

As the investigation continues on the possible U.S. strike on an Iranian girl's school, the White House continues to insist that the U.S. "does not target civilians," and said the investigation has "no conclusions at this time."

This comes amid reports that say preliminary findings have found the U.S. responsible for the strike.

“This investigation is ongoing. There are no conclusions at this time, and it is both irresponsible and false for anyone to claim otherwise. As we have said, unlike the terrorist Iranian regime, the United States does not target civilians," White House spokeswoman Anna Kelly said in a statement.

Iran's national football team will not take part in the upcoming World Cup, due to the current situation following recent U.S.-Israeli attacks, Iran’s Sports and Youth Minister Ahmad Donyamali said Wednesday.

Donyamali added that recent developments show “the conditions are not suitable” for Iran’s national team to participate in the tournament, the official state Islamic Republic News Agency reported on Wednesday.

"Our team members have no security at all to attend the World Cup," he said, as the semi-official ISNA News Agency reported Wednesday.
