North Korea fired about 10 short-range ballistic missiles toward the sea off its east coast on Thursday, South Korea's military said. The Associated Press, in a story carried by ABC News, and DW reported the launches.

South Korea's Joint Chiefs of Staff said the missiles were fired from near the coastal town of Wonsan. The AP reports each flew about 155 miles. DW reports the launch came at about 12:30 pm local time, which was 11:30 pm Wednesday Eastern Time.

South Korea's military said it is watching for more launches and sharing information with the United States and Japan. Japan's Defense Ministry said the missiles fell outside its exclusive economic zone, DW reports, citing South Korea's Yonhap news agency.

The launches come as ties between the two Koreas worsen. Three South Korean soldiers were wounded on September 21 when land mines went off in the Demilitarized Zone. DW reports a joint South Korean and United Nations probe found North Korea had planted the mines south of the border line. Pyongyang denies it and has warned of retaliation.

Last week, North Korea said it would restart propaganda loudspeaker broadcasts along the border and put new weapons there. South Korea offered talks to clarify the border, but the North has not answered. AP journalists saw North Korean artillery guns on the border that had not been visible before.

DW reports the North has tested missiles more than 10 times this year, most recently on October 12. The AP notes leader Kim Jong Un visited China last weekend to push for closer ties. President Trump has said he wants to restore diplomacy with Kim.

What we know: South Korea says the North fired about 10 short-range ballistic missiles from near Wonsan on Thursday.
What we don't: What type of missiles they were, and whether more launches will follow.
