(CNN) North Korea test fired several short-range projectiles Saturday morning from the country's eastern coast, according to South Korean officials.

The projectiles flew 70 to 200 kilometers (43 to 125 miles) before crashing into the sea, officials said, adding that both South Korean and US authorities were analyzing the details to glean further insights. The launch took place around at 9:06 a.m. (8:06 p.m. ET Friday).

If confirmed, the test is understood to be the first missile launch from North Korea since late 2017 -- and the first since US President Donald Trump began meeting the country's leader Kim Jong Un.

The move could escalate tensions with the United States, coming two months after Trump walked away from a second summit between the two leaders.

"At present, our military has intensified surveillance and vigilance to prepare for North Korea's additional launches," South Korea's Joint Chiefs of Staff said in a statement, adding that Seoul and Washington were "working closely together and maintaining their full preparedness."
