WASHINGTON DC, USA - The United States and its allies have imposed new sanctions on Myanmar's military rulers as the conflict escalates two years after the military seized power in a coup.

Sanctions were levied against six individuals and three entities "connected to the regime's efforts to generate revenue and secure arms," according to a statement issued by U.S. Secretary of State Antony Blinken.

Officials from the military's lucrative energy firm Myanmar Oil and Gas Enterprise (MOGE), its Mining Enterprise 1 and 2, and the air force were among those targeted.

Reflecting growing concern about the devastation caused by air raids 11 children were killed last September when a school in the Sagaing region was hit by a bomb Canada and the United Kingdom imposed new restrictions on the supply and sale of aviation fuel.

The U.K. targeted units of the Asia Sun Group, which dominates the aviation fuel sector in Myanmar. At the same time, Canada suspended direct and indirect supply, sale, or transfer of aviation fuel in the country, including transit, transshipment, and brokering.

Amnesty International's business and human rights researcher Montse Ferre applauded the focus on aviation fuel and urged other countries to follow Canada's lead.

"This suspension must be maintained until effective mechanisms are in place to ensure that aviation fuel is not used to carry out air strikes that constitute serious violations of international human rights or humanitarian law," she said.

Australia was also among the countries that announced new sanctions two years after a military coup deposed Aung San Suu Kyi's elected National League for Democracy (NLD) government and plunged the country into crisis.
