Foreign diplomats in South Korea are watching closely how the situation on the Korean Peninsula will unfold after North Korea claimed that it has successfully tested a hydrogen bomb, Wednesday.
Immediately after the North's announcement, foreign diplomatic missions in Seoul reported it to their governments and discussed the situation for the whole day. Some missions said they are working with their governments to make official announcements.
Joon Hetland, first secretary at the Embassy of Norway, said that the mission is watching over the news, but cannot give further comment due to the sensitivity of the issue.
"Our foreign Minister Borge Brende tweeted about the North's claims two hours after the announcement," he said.
The minister said on his twitter account: "North Korea claims it has tested a nuclear bomb. The hydrogen bomb is a serious threat to global security."
The British Embassy said that they are aware of the situation in North Korea.
"We are waiting for the Foreign and Commonwealth Office to make an official announcement," Jenny Hong, senior media officer at the British Embassy said.
The Embassies of Canada, Turkey, Ecuador and Egypt said they are watching the North's claims while waiting for official statements from their home countries.
"Our ambassador Oscar Herrera Gilbert is aware of the situation in North Korea and is keeping a close eye on it," Ana Diaz, third secretary at the Embassy of Ecuador, said.
"Our deputy head of the mission fully knows about the claims and we are waiting for the Turkish government to make an official statement," Seyla Saglik, third secretary at the Turkish Embassy, said.
The Embassy of Georgia also said they are keeping an eye on the issue.
"We cannot say anything at this time as this is a very sensitive issue," Zaal Tchkuaseli, counselor at the embassy said.
North Korea made the announcement within three hours after the test that was performed at 10 a.m., which was initially identified as an earthquake, then categorized as an artificial earthquake. The test occurred near Gilju, where the North conducted three previous nuclear tests.
The North said the hydrogen bomb is a legal, self-defensive right and an irrefutably justified measure.
North Korean leader Kim Jong-un suggested last month that his hermit state has been developing an H-bomb, which was met with skepticism by international experts.
A thermonuclear weapon uses more advanced technology to cause a bigger explosion than an atomic bomb.
