"But being with colleagues from the London fire brigade when I was in there, colleagues from the London ambulance service and other police officers, I think it's fair to say it is incredibly emotional working in there".
Britain's trade minister says the exterior paneling used on the exterior of the London high-rise, in which dozens were killed in a fire, appears to have violated building rules.
"We have been from the top to the bottom of Grenfell Tower".
Experts believe the exterior cladding, which contained insulation, helped spread the flames quickly along the outside of the tower in the June 14 blaze.
"We are supporting the families and the loved ones of each of those 79", Metropolitan Police Commander Stuart Candy said in a statement.
Khan has praised the heroism of Christians, Muslims and others in looking after people affected by the Grenfell Tower disaster, reported The Independent. It may take longer than that.
Speaking as he left the church with his wife Saadiya, Khan said: "I've spent time with the local community, not just the Christian congregation, but members of all faiths here at the church, grieving, sharing their stories". Survivors of the building claim that cheap materials for the cladding and a lack of maintenance on the building were to blame for the fatal fire.
The Metropolitan Police confirmed earlier in the week that 58 people are confirmed dead or presumed dead in the fire and authorities fear the death toll will rise. He asked anyone who was in the tower and survived to contact police immediately. "The reason we had to pause the search and recovery yesterday was for the safety of our staff".
While emergency services have been widely praised for their handling of the disaster, the government has been criticized for a slow and inadequate response, with Prime Minister Theresa May facing public anger for failing to meet residents during her first visit to the site. "It is", he said, after one volunteer near the apartment block demanded to know where those left homeless were going to go.
May said after the meeting Saturday that there have been "huge frustrations" in the community as people tried to get information.
Meanwhile, the Home Office said it was making arrangements for the family of one of those who died in the fire to travel from Syria to Britain for his funeral.
British health authorities say that 19 fire survivors are still being treated at London hospitals, and 10 of them remain in critical condition.
The 23-year-old Alhajali is the only victim of the Grenfell Tower fire to be officially named as the hard process of identifying human remains continues. This relies on dental records, fingerprints and DNA when possible and also features like tattoos or scars.
