For his part, Mr Johnson visited Myanmar and the ravaged Rakhine state earlier this month to press the country's de facto leader Aung San Suu Kyi on allowing Rohingya refugees to safely return to their homes.
Myanmar's government is using bulldozers to erase dozens of villages in Rakhine state in a vast operation that rights groups say is destroying evidence of mass atrocities against the ethnic Rohingya Muslim minority.
"Ministers will call on [Federica] Mogherini to propose restrictive measures on senior members of the Myanmar military for systematic human rights abuses, without delay", one diplomat said on Thursday, referring to European Union sanctions.
The report stated that over 534,000 Rohingya children are living in refugee camps in Bangladesh, while almost 185,000 Rohingya children remain in Myanmar's Rakhine state, subjected to ongoing violence.
Chris Lewa, whose Arakan Project monitors the persecuted Muslim minority's plight, said the degree to which the villages had been razed would make it even harder for the Rohingya, who have no citizenship and few rights, to ever reclaim their land.
State media and the Office of the President have also reported construction in several areas across Rakhine State, some of which has been focused on road improvements and has involved clearing villages. As satellite photographs show, a return home might be simply impossible.
Any bulldozing of villages that have destroyed evidence of crimes is apparent obstruction of justice, Human Rights Watch said. "Conditions are not yet conducive to the voluntary repatriation of Rohingya refugees", Grandi told members of the Security Council. Many Rohingya fear authorities are seizing land they've lived on for generations.
In response to HRW's report, Maung Ohn, a Rakhine state lawmaker who represents Maungdaw township where new structures for returning refugees are being built, also said the demolitions are part of the project to build new houses for refugees.
"The wild elephant trampled a Rohingya child to death. and then trampled another Bangladeshi man to death when it was chased by Rohingya refugees and local villagers", Ali Kabir, the district forest department chief, told AFP.
"Government and allied forces, including Russian Federation, carried out indiscriminate attacks and direct attacks on civilians and civilian objects using aerial and artillery bombing, including with chemical and other internationally banned weapons, killing and injuring hundreds", Amnesty's report says. The Burmese government has failed to credibly investigate serious alleged abuses committed by security forces since August 25, which Human Rights Watch has found the amount to crimes against humanity.
"The warning signs in Myanmar had always been visible: massive discrimination and segregation had become normalised within a regime that amounted to apartheid, and for long years the Rohingya people were routinely demonised and stripped of the basic conditions needed to live in dignity".
