The White House has applauded the move.

But he has failed to convince the third placed contender – Lee Jun-seok – to abandon his bid and back the PPP to improve its chances. The New Reform Party’s Lee, who is 40 years old, said on Tuesday there would be “no candidate merger” with “those responsible for the emergency martial law”.What about foreign policy?

Although policy debates have taken a backseat, the outcome of the election could reorient South Korea’s approach towards North Korea. The two neighbours are technically in a state of war as the Korean War of 1950-1953 ended in an armistice rather than a peace treaty, and ties between them are at a new low.North Korean leader Kim Jong Un has called for rewriting his country’s constitution to scrap the longstanding goal of unifying the war-divided nations and described Seoul as an “invariable principal enemy”. Pyongyang has also severed communication lines, and the two countries have clashed over balloons and drones carrying rubbish and propaganda.Lee of the Democratic Party has promised to ease tensions if elected, including by restoring a military hotline, and committed to maintaining the goal of eliminating nuclear weapons from the Korean Peninsula.

Kim, however, has backed Yoon’s hardline approach, promising to secure “pre-emptive deterrence” through tools such as ballistic missiles and the redeployment of US tactical nuclear weapons. He has said he would also seek a path for the country to pursue nuclear armament by securing the right to reprocess nuclear fuel, a key step towards building atomic weapons.The two candidates also differ in their approach to the US, the country’s most important security ally, and to China, its biggest trading partner.

Lee, who espouses what he calls a pragmatic foreign policy, has said it is crucial to maintain South Korea’s alliance with the US and pursue security cooperation with Japan. However, he has pledged to prioritise “national interests” and said there’s “no need to unnecessarily antagonise China or Russia”.

Kim, meanwhile, has questioned Lee’s commitment to the US-South Korea alliance, and has promised to hold an immediate summit meeting with US President Donald Trump if elected to discuss tariffs.At least 115 people have been killed after heavy flooding submerged the market town of Mokwa in Nigeria’s northcentral Niger State, destroying thousands of homes, according to an emergency services official, in a country beset by deadly storms every year.

Head of the operations office in Minna, capital of Niger State, Husseini Isah, said on Friday that many people were still in peril as rescue efforts continue.“We have so far recovered 115 bodies and more are expected to be recovered because the flood came from far distance and washed people into the River Niger. Downstream, bodies are still being recovered,” a Niger State Emergency Management Agency (SEMA) spokesman, Ibrahim Audu Husseini, told the AFP news agency. “So, the toll keeps rising.”

Torrential rains battered Mokwa late on Wednesday and lasted for several hours, washing away dozens of homes, with many residents still missing. A dam collapse in a nearby town caused the situation to rapidly deteriorate.It is difficult to say how well-placed rescue efforts are to salvage people “because every rainy season we continue to see things like this,” said Al Jazeera’s Ahmed Idris, reporting from Abuja.
