The Palestinian National Authority would have prevented a deadly attack on a Jewish settlement if it had information in advance, President Mahmoud Abbas said Monday.

"If we had known, we would have prevented it using all our ways, " Abbas said in an interview with Israel Radio. "We want to know who committed the operation," Abbas added, referring to the stabbing of five Israeli settlers, members of one family, to death in the West Bank settlement of Itamar early Saturday.

Abbas said he agreed with Israeli Prime Minister Benjamin Netanyahu to launch a joint investigation in the incident. "This is inhuman, immoral and low act," Abbas continued.

"I cannot see a four-month-old infant being killed, if they told me watch this on the television, I won't be able to," Abbas said, referring to the killing of the youngest child of the Jewish family.

Abbas, meanwhile, said he does not believe that a wave of " terror attacks" would be seen in the meantime, vowing not to allow this to happen.

He also rejected Israeli "claims" that the PNA allows incitement against the Jewish state inside the West Bank mosques, calling for forming a joint committee comprising the United States to check the so-called incitement to hatred in Palestinian textbooks.
