David Cameron claimed that Labour leader Jeremy Corbyn is "security-threatening, terrorist-sympathising and Britain-hating".
The prime minister criticised Jeremy Corbyn for saying, in 2011, that the fact that Osama Bin Laden was killed by US forces, rather than brought to trial, was a "tragedy".
Mr Cameron argued that the "real tragedy" was the deaths caused by the September 11 attacks.
