Indian Naval Ship (INS) Sunayna arrived at Port Louis, Mauritius, on April 26, 2025, after completing Phase I of Joint Exclusive Economic Zone (EEZ) surveillance with the National Coast Guard (NCG) Mauritius, the Ministry of Defence announced. This visit strengthens regional maritime cooperation and capacity-building with nations in the South Western Indian Ocean.

INS Sunayna, which sailed from Karwar on April 5, is carrying 44 naval personnel from nine Indian Ocean Region nations, including Mauritian officers and sailors. The ship and its multinational crew received a warm welcome from senior Mauritian officials and the Indian High Commission.

During the two-day port call, activities include official meetings, squadron visits, joint yoga sessions, trekking, and friendly sports events. The ship will also be open to public visitors. After Mauritius, INS Sunayna will begin Phase II of Joint EEZ surveillance and then sail to Seychelles.

INS Sunayna is a Saryu-class Naval Offshore Patrol Vessel equipped for anti-piracy, maritime surveillance, and humanitarian missions, featuring advanced weaponry, electronic warfare systems, and helicopter support.

The Indus Waters Treaty (IWT), signed in 1960 between India and Pakistan, governs the sharing of the Indus River system. Brokered by the World Bank, the treaty grants Pakistan control over the western rivers (Indus, Jhelum, and Chenab) while India retains rights over the eastern rivers (Ravi, Beas, and Sutlej). Despite tensions, the treaty has remained intact for over six decades.

Recent Developments

Following the Pahalgam terror attack on April 22, 2025, India has suspended the Indus Waters Treaty, citing Pakistan’s continued support for cross-border terrorism. The Indian government formally notified Pakistan of this decision, stating that the treaty’s fundamental assumptions have changed due to demographic shifts, clean energy needs, and security concerns.

India’s move has strategic implications, as it could disrupt Pakistan’s irrigation, reservoirs, and hydropower projects. The suspension also allows India to exercise greater control over water resources, including flushing reservoirs and modifying hydropower project designs.

Pakistan has retaliated diplomatically, suspending trade ties and visa agreements with India. The situation remains fluid, with India signaling that the treaty could be reinstated if Pakistan ceases its support for terrorism.

Dr. K. Kasturirangan, former ISRO Chairman and a key contributor to India’s National Education Policy, passed away at age 84 at his residence in Bengaluru on April 25, 2025. As ISRO Chairman, he was instrumental in the development of the Polar Satellite Launch Vehicle (PSLV) and led the Indian Space Programme for over nine years, stepping down in August 2003.

He also served as Chancellor of JNU, Chairman of the Karnataka Knowledge Commission, Director of the National Institute of Advanced Studies, and was a Rajya Sabha member from 2003 to 2009.

The Defence Research and Development Organisation (DRDO) has achieved a major milestone in hypersonic technology by successfully conducting ground testing of an active cooled scramjet subscale combustor for over 1,000 seconds. This test, conducted at DRDL Hyderabad in a new state-of-the-art Scramjet Connect Test Facility, builds on a previous 120-second test in January.

The achievement brings India closer to developing a full-scale flight-worthy scramjet engine. Defence Minister Rajnath Singh praised the DRDO, industry, and academia, calling it a testament to India’s commitment to developing critical hypersonic weapon technologies.

Hypersonic cruise missiles, which travel at speeds over Mach 5, rely on air-breathing propulsion systems like scramjets, and this test validates both the long-duration combustor design and the new testing infrastructure.

The National Zero Measles-Rubella Elimination Campaign 2025–26 was launched on 24 April 2025 in New Delhi, marking the start of World Immunisation Week. The campaign aims to eliminate Measles and Rubella by 2026 by ensuring 100% immunisation coverage with two vaccine doses for children.

Health Minister J. P. Nadda, launching the campaign virtually, noted that 332 districts reported zero measles cases and 487 districts zero rubella cases from January to March 2025. He urged public involvement (Jan Bhagidari) and the participation of MLAs, MPs, and local leaders to spread awareness.

Measles and Rubella are highly infectious viral diseases that can lead to serious health issues or death. Under the Universal Immunisation Programme, vaccines are provided free of cost at 9–12 months and 16–24 months of age. In 2024, India recorded a 73% drop in Measles and a 17% drop in Rubella cases compared to 2023.

Following the Pahalgam terror attack, the Indian government has implemented strong retaliatory measures. On April 23, 2025, the Cabinet Committee on Security (CCS), chaired by Prime Minister Narendra Modi, reviewed the situation and directed all security forces to remain on high alert.

India has suspended the Indus Waters Treaty (1960) and shut down the Integrated Check Post at Attari with immediate effect. Additionally, Pakistani nationals are no longer permitted to travel to India under the SAARC Visa Exemption Scheme (SVES), and previously issued SVES visas to them are now cancelled. Pakistani nationals in India under this visa scheme must leave the country within 48 hours.

The CCS highlighted the cross-border links of the terror attack, which coincided with Jammu and Kashmir’s peaceful elections and developmental progress. The attack was condemned strongly, and international support has poured in, with many countries expressing solidarity and a zero-tolerance stance on terrorism.

On April 22, 2025, a terrorist attack in Pahalgam, Jammu and Kashmir, left the nation in shock. Armed militants opened fire on tourists at Baisaran, a scenic meadow, resulting in at least 24 civilian deaths and multiple critical injuries.

The attack, described as one of the worst in recent years, has sparked widespread shock and outrage across India. No group has claimed responsibility yet.

Prime Minister Narendra Modi has cut short his Saudi Arabia visit to return to Delhi and address the situation. Jammu and Kashmir Chief Minister Omar Abdullah called the incident “much larger than anything we’ve seen directed at civilians in recent years.”

Although Kashmir has experienced a long-running insurgency, attacks specifically targeting tourists are rare, making this tragedy even more alarming.

On April 22, 2025, the Union Public Service Commission (UPSC) officially announced the final results of the Civil Services Examination 2024.

Prime Minister Narendra Modi departed for a two-day official visit to Saudi Arabia on April 22, 2025, aiming to strengthen the growing strategic partnership between the two nations. In his departure statement, he highlighted the importance of India-Saudi Arabia ties, which now encompass defence, trade, investment, energy, and people-to-people connections.

PM Modi emphasized his intent to engage with the Indian diaspora in Saudi Arabia and attend the 2nd Meeting of the Strategic Partnership Council, building on Prince Mohammed bin Salman’s 2023 visit to India.

He is set to arrive in Jeddah, marking the first visit by an Indian Prime Minister to the commercial hub in over 40 years. The visit includes a factory tour and interaction with Indian workers.

India’s investments in Saudi Arabia reached around USD 3 billion by August 2023, spanning key sectors like IT, telecom, pharmaceuticals, construction, and consultancy, underlining the countries’ deepening economic cooperation.
