Background
The Suez Canal Authority records that digging of the canal began on 25 April 1859 at Al-Farama, the city now called Port Said, with 20,000 Egyptians taking part in the groundbreaking. The canal was inaugurated on 17 November 1869. The Authority lists nationalisation as the most notable turning point in its history, followed by the canal's closure after the 1967 war and its reopening in June 1975. The idea of linking the Red Sea and the Mediterranean is traced to the Egyptian Pharaoh Senausert III of the Twelfth Dynasty. Necho II attempted a re-digging in 610 BC, Darius I in 510 BC and Ptolemy II in 285 BC, and the Roman Emperor Trajan re-dug it around 98 AD. Amr Ibn El-A'as reopened it for navigation in 641 AD.
Digging began:
25 April 1859, at Al-Farama (Port Said)
Inauguration:

Excavators at Behbeit al-Hagar in Egypt's Gharbiya governorate recovered a 1.6-metre-tall statue head of King Ramses II wearing the Double Crown, known as the Pschent. Scholars estimate the complete statue originally stood about 8.5 metres tall. The rear pillar of the head carries the king's Horus name, Hor-Ka-Nakht Mery-Maat. A 2.4-metre torso and head of a second royal statue wearing the Nemes headcloth was also found, along with a 1.3-metre pink granite block inscribed with the royal titles Nesu-Bity, meaning King of Upper and Lower Egypt, and Sa-Re, meaning Son of Ra. A local citizen first reported the granite block to the Ministry of Tourism and Antiquities, which allowed rescue excavations to begin. The find shows Ramses II used monumental statuary to assert authority in the Delta, away from southern centres such as Luxor and Abu Simbel.

India's first Petroglyph Conservation Park, at Sindhu Ghat in Leh, was to be dedicated to the nation on 15 October 2026 as one of the five Ladakh projects, the Prime Minister's Office announced on 14 October 2026.
It is meant to protect Ladakh's prehistoric rock carvings and to encourage responsible heritage tourism.
Lieutenant Governor Vinai Kumar Saxena had laid the foundation stone on 18 April, World Heritage Day.
Relocation of endangered petroglyphs began from Saboo Thang, with 31 carvings moved first.
The first phase plans to shift 155 petroglyphs, from sites including Phyang Thang, Stakmo Thang, Likir Hill, Likir Thang and Taru Thang, and from Thiksey, Spituk and Khaltse.
The carvings measure 4 to 17 feet in circumference and weigh between 500 kg and 10 metric tonnes.
Most depict wildlife such as ibex, yak, argali and blue sheep, along with hunting scenes and footprints, and the threats listed are weathering, unregulated tourism, construction and human interference.
Ladakh's petroglyphs occur at altitudes from 2,500 metres to over 5,000 metres.

Background
The Kingdom of Saba flourished in what is now Yemen from the 1st millennium BCE until the arrival of Islam around 630 CE.
UNESCO inscribed "Landmarks of the Ancient Kingdom of Saba, Marib" in 2023 under cultural criteria (iii) and (iv).
It is a serial property comprising seven archaeological sites.
Ma'rib was the walled capital city of Saba, while the fortified city of Sirwah may have served as its military capital.
The Ma'rib dam fed an irrigation system of canals that supported the largest ancient man-made oasis.
The temples of Awām, Bar'ān and Ḥarūnum are among the inscribed landmarks.
Saba's wealth rested on the Incense Trade Route, broadly between the 8th century BCE and the 3rd century CE.
The property was placed on the List of World Heritage in Danger from the time of its inscription.
Inscribed:
2023
Criteria:
(iii), (iv)
Component sites:
Seven archaeological sites

Background to the Kerala High Court proceedings this week on the Crime Branch investigation into a State Planning Board recruitment examination conducted by the Kerala Public Service Commission.
The Kerala Public Service Commission was formed on 1 November 1956, when the State of Kerala came into being, by transforming the Travancore-Cochin Public Service Commission into it.
In Travancore, a Public Service Commissioner selected candidates for direct recruitment to government posts, and G.D. Nokes was appointed the first Commissioner on 14 June 1936.
In Cochin, a Staff Selection Board was set up in 1936 for initial recruitment to lower posts, and a three-member Cochin Public Service Commission was constituted in 1947 under an Act of the State Legislature.
After Travancore and Cochin merged on 1 July 1949, a three-member Commission including the Chairman was created by Ordinance, exercising broadly the functions set out in the Government of India Act, 1935; it continued under constitutional provisions from 26 January 1950.
The strength of the Commission was raised in stages — five members in 1959, seven in 1971, eight in 1981, nine in 1982, thirteen in 1983 and fourteen in 1984 — reaching the present strength of eighteen in 2005.

Background
Al Zubarah Archaeological Site was inscribed on the UNESCO World Heritage List in 2013 under criteria (iii), (iv) and (v). It is a walled coastal town on the Persian Gulf that flourished as a pearling and trading centre in the late eighteenth and early nineteenth centuries, founded by Utub merchants from Kuwait. At its height it traded high-value goods, above all pearls, with the Indian Ocean, Arabia and Western Asia. Al Zubarah was mostly destroyed in 1811 and finally abandoned in the early twentieth century, and only a small part of it was resettled in the late nineteenth century. UNESCO describes it as the only remaining complete urban plan of an Arabian pearl-merchant town. A short distance away stand the remains of the fort of Qal'at Murair, which shows how the desert's water supplies were managed. The inscribed property covers 415.66 hectares with a buffer zone of 7,196.4 hectares, and only a small part of the site has been excavated.
