LONDON (Reuters) - Visiting South African cricketers "are uneasy" following Monday's suicide bomb attack on a pop concert in Manchester but abandoning their tour of England is not under consideration, the team's manager has said.

Britain has increased its security threat level to "critical" from "severe" following the attack that killed 22 people at an Ariana Grande concert at the Manchester Arena.
