It said all the families affected have been contacted and trained officers are supporting them.

Officials said 22 people were killed in the suicide bombing of an Ariana Grande concert at Manchester Arena, including teenagers and children. Some of them have been named by friends and family. The youngest victim was 8-year-old Saffie Roussos.

Manchester health officials have raised the number of wounded in the concert bombing, saying 119 people sought medical treatment at the city's hospitals after the suicide attack Monday night.

The Greater Manchester Health and Social Care Partnership gave the higher figure on Wednesday.

Jon Rouse of the agency said 64 people were still hospitalized. He said the number of overall wounded was raised due to the "walking wounded" who came in hours after the attack.

Israel's defense minister says he doubts the devastating bombing in Manchester will have any impact on European counterterrorism tactics because of the continent's "politically correct" character.

Avigdor Lieberman says every bombing in Europe results in much talk, but little action. He told Israel's Army Radio Wednesday the problem is extremism among Muslim youths who are not integrated into society.

He said nothing will change until these residents are ready to adopt "universal, European values."

At least 22 people were killed in Monday evening's attack at an Ariana Grande concert. The bomber, Salman Abedi, was British-born and of Libyan descent. The official threat level in Britain has since been raised to its highest point.

Lieberman says Israel and Britain enjoy close intelligence cooperation and Israel offered its assistance following the attack.
