MPs are now debating shadow home secretary Diane Abbott's question on knife crime.
Home Office Minister Victoria Atkins says "the senseless killings in recent days have shocked the country."
There is no denying the urgency of this issue, she adds, noting the government is "day in, day out" acting to end the bloodshed.
The government is taking "a tough law enforcement approach," he adds, including knife prevention orders being added to the Offensive Weapons Bill.
"We recognise that we cannot arrest our way out of this," she adds, noting that £220m is being invested into early intervention projects so young people are not "sucked into crime".

What does the government's defeat on amendment 13 mean?
Sean Curran
Parliamentary correspondent
The government's defeat on a Labour amendment to the Trade Bill which calls on the government to negotiate a new customs union with the EU means MPs will get the chance to vote on whether or not the UK should remain in the customs union when the Trade Bill returns to the Commons.
Peers backed an amendment to the Trade
Bill which calls on the government to negotiate a new customs union with the
EU.
Labour had put forward the proposal with
cross party support.
The amendment was approved by 207
votes to 141, a majority of 66.

International Trade Minister Baroness Fairhead says the amendment would require disputes to be heard by UK courts which "has the potential to undermine a successful and internationally accepted framework".
The government supports calls for fair outcomes for claims, she adds, noting they "continue to push hard for transparency".
The Trade Bill is not here to deal with future trade agreements, she says, adding that due to this, and the fact there are processes already in place for complaints, Lord Stevenson should remove his amendment.
Lord Stevenson agrees to withdraw his amendment on the promise of further discussions with Baroness Fairhead.

Labour peer Lord Stevenson of Balmacara says he feels sorry for Lord Bates having to speak against this amendment this evening.
On the fact that MPs have voted on customs union membership post-Brexit before, Lord Stevenson says "when the facts change, so do opinions".
He adds that the minister's argument that membership of a customs union would cause more uncertainty is inaccurate as "surely it is better to have a certain target".
Concluding his speech, Lord Stevenson of Balmacara says he wishes to test the views of the House and pushes his amendment 13 to a vote.
Peers divide to vote on amendment 13. The result is expected in around 10 minutes.
'Reopening negotiations would increase uncertainty' - Minister
Trade Bill
House of Lords
Parliament
HoLCopyright: HoL
International Development Minister Lord Bates says the arguments for and against a customs union has not changed and that the government's position is clear.
The people of the UK voted to leave, to take back control of their laws and have an end to a freedom of movement, he says, noting that a customs union would not allow this.
Lord Bates says the Commons has already voted against the UK's membership of a customs union.
He adds that he accepts uncertainty is damaging for businesses, yet this proposal "at the eleventh hour, when in sight of an agreement, requires the government to reopen the whole negotiation process".
This will not help businesses, he says, "it would cause more uncertainty".
