Kieran McCarthy MLA said: “This was a despicable attack. Those involved showed absolutely no regard for human life and we must unite again in condemning this evil act.
“This attack is another clear reason why we need a deal to safeguard the Assembly. It must focus minds because people must realize that the best way to end violence is to continue progress in the peace process. A vacuum would be a nightmare and would play into the hands of these evil elements.
“Anyone who can help catch these terrorists must contact police immediately.”
