The tests of short-range missiles came a day before South Korea holds parliamentary elections amid the coronavirus pandemic.

South Korea has decided to go ahead with voting on Wednesday even though many other countries, including Britain and France, have postponed elections because of the coronavirus epidemic.
South Korea is not in lockdown, and its governing Democratic Party is hoping that the countrys successful efforts to contain the virus early will help its candidates on Wednesday, bolstering President Moon Jae-ins grip on power.
Voters are being required to wear masks and use sanitizer and plastic gloves before casting their ballots. Those under self-quarantine will be allowed to leave their homes with government escorts to vote after 6 p.m. Wednesday, when the balloting for the general public ends.
Nearly 27 percent of the countrys 44 million eligible voters already cast their ballots on Friday and Saturday in advance voting to avoid the crowds on Wednesday.
North Korea carried out no weapons tests in 2018, when its leader, Kim Jong-un, was engaged in diplomacy with President Trump. But it resumed short-range missile launches last May, three months after Mr. Kims second summit with Mr. Trump, held in Vietnam, collapsed over differences on how to denuclearize North Korea and when to ease American-led international sanctions.
