Kathmandu, Sep 27: Nepali authorities have issued a special flood warning after the Narayani River crossed its danger level in parts of southern Chitwan and Nawalparasi districts, with the water level continuing to rise.

Flooding in the transboundary river, known as the Gandak in India, could also affect downstream areas in the neighbouring country.

The National Disaster Risk Reduction and Management Authority (NDRRMA) issued the flood warning on Sunday morning and urged residents living along the banks of the Narayani River to move away from the river and to higher ground, considering the risk to lives and property.

According to a special flood forecast and advisory bulletin issued by the Centre of Hydrology and Water Resources Research (CHWRR) at 7:45 a.m. Sunday, the water level of the Narayani River had risen to around 11 metres, well above the designated danger level of 9 metres.

The CHWRR said the water level at the Devghat flood monitoring station in Chitwan district is expected to keep rising until this afternoon and could peak at about 13 metres around 11 a.m.

“There is a high likelihood that the water level will remain above the danger level until the evening,” the CHWRR said, adding that high flows are also expected to continue in the Narayani’s tributaries through the afternoon.

The Kali Gandaki River, one of the Narayani’s major tributaries, has recorded a flow significantly above its danger level, while the Seti, Madi, Marsyangdi, Daraundi and Chepe rivers are flowing above their warning levels and continue to rise. The Budhi Gandaki and Trishuli rivers have also approached their warning levels, with flows continuing to increase.

The CHWRR said the high flow has created a high risk of flooding and inundation in low-lying and flood-prone areas along the Narayani River in Chitwan and Nawalparasi East and West districts—all three districts border India.

Nepali authorities have also advised people to avoid travelling along the banks of the Narayani and its tributaries and to avoid unnecessary movement near riverbanks, bridges, embankments and other vulnerable locations.

People living along the Kali Gandaki, Seti, Madi, Marsyangdi, Daraundi, Chepe, Budhi Gandaki and Trishuli rivers and their tributaries have been urged to remain on high alert until the evening.

The authorities have asked residents to follow flood-related information and instructions issued by local administrations, security agencies and other relevant authorities.

Nepal, which was hit hard by devastating floods in the Bhotekoshi and Trishuli rivers, has been experiencing incessant rainfall in several parts of the country since September 24.

A rainfall-triggered landslide buried a house in Bhaskatta, Mathagadhi Rural Municipality, Palpa district, in western Nepal early Sunday, leaving three people missing, Nepal Police said. A police team has been deployed to carry out the rescue operation, police said.

Meanwhile, flooding in the Kali Gandaki River swept away 25 houses in the Farse area of Jaljala Rural Municipality-8 in Parbat district, according to police. “Of the approximately 80 houses in the settlement, 25 have been swept away, while the remaining houses are at risk,” police said.

“No human casualties have been reported, and all residents of the settlement have been relocated to a safe location,” police added.

Tehran, Sep 27: The Secretariat of Iran’s Supreme National Security Council (SNSC) denied in a statement that Iran would take military retaliatory action in response to the recent aviation restrictions imposed on the country, the semi-official Tasnim news agency reported.

The SNSC issued the statement in response to certain “misleading” interpretations and quotes from recent remarks by its Secretary Mohsen Rezaei regarding the air transport issue, which have given rise to questions and ambiguities.

It said the claim that Iran would resort to military retaliation in response to recent aviation restrictions was rejected, adding that negotiations with relevant countries were being pursued seriously to remove certain “illegal” aviation restrictions, Xinhua news agency reported.

The SNSC underlined that there were numerous non-military ways to retaliate against those complying with the restrictions, which could be applied to certain airports if necessary, while expressing hope that the situation would not reach that point.

Earlier this week, US Treasury Secretary Scott Bessent said that “all the Iranian airlines will be shut down around the world” from Wednesday, threatening to impose secondary sanctions on companies that provide them with aviation services.

He told broadcaster CNBC that when Iranian carriers land at an airport, “you cannot provide them with fuel, you cannot provide them with landing services, you cannot sell them tickets, or you will be knocked out of the dollar system.”

In an interview with state-run IRIB TV on Wednesday hours after the US sanctions on Iranian airlines took effect, Rezaei called on countries, especially Iran’s neighbors, not to join the U.S. “adventurism” as it would soon be doomed to failure.

Meanwhile, US President Donald Trump has reportedly rejected Iran’s proposal for a seven-day ceasefire and is likely to resume bombing Tehran after the November midterm elections in the US.

The Wall Street Journal reported that Trump had rejected the proposal, citing US officials familiar with the matter.

Trump, who has vowed that Iran will never acquire a nuclear bomb, was sceptical that Tehran would meet his demands and considers a renewed bombing campaign likely, according to the report.

He also posted an image on his Truth Social platform showing a map with the Strait of Hormuz circled and labelled “Trump Strait.”

Moscow, Sep 26: Russian President Vladimir Putin said that an escalation of tensions would not achieve the outcome sought by Kyiv and could only worsen the situation in Ukraine.

“They must understand that no provocative acts or escalation of tensions will deliver the outcome they seek. Such moves will only make the situation worse for them,” Putin said at a press briefing on Friday.

He said Russia’s military responses had prompted Kiev to seek ceasefire arrangements covering several areas, including attacks on energy facilities and airstrikes, Xinhua news agency reported.

Russia has begun responding to what he described as actions taken by Ukraine, including an alleged bid to impose a naval blockade and strikes on storage facilities and civilian infrastructure, he said, adding that, according to Russian assessments, Ukraine had damaged more than 100 vessels in the Black Sea.

Earlier this month, Moscow said that sanctions on Russia’s oil and gas exports will not revive relations with the United States or lead to peace with Ukraine.

US President Donald Trump signed the Russia sanctions bill into law. The legislation targets Russia’s energy and defence industries, as well as its “shadow fleet” of tankers.

Kremlin spokesperson Dmitry Peskov said that Russia has largely adapted to the sanctions and found ways to minimise their impact, adding that the country’s trading partners oppose such restrictions.

Earlier in the day, Ukrainian President Volodymyr Zelensky said that he President Trump had agreed to meet in New York, and said Ukraine was ready to take serious steps towards peace in coordination with the American team.

“We agreed to meet in New York, and this meeting could change a lot. There is diplomatic momentum,” Zelensky said in a post on X after speaking with Trump.
