Mauritius has announced that its national flag will fly at half-mast at all government offices and institutions till sunset on Saturday as a mark of respect to India's former prime minister Manmohan Singh.  Bhutan's national flag was flown at half-mast across the country, its embassies and consulates abroad, according to the Royal Bhutan government as a mark of respect to the departed.

In a note, Mauritius Prime Minister Navin Ramgoolam's office also urged the private sector to fly the flags at half-mast.

Mauritius Foreign Minister Dhananjay Ramful travelled to Delhi and paid respects to the former prime minister.

"Following the passing away of Dr Manmohan Singh, former Prime Minister of the Republic of India, the public is hereby informed that the Mauritius Flag will be flown at half-mast on all government buildings until sunset today Saturday, the day of his funeral," the Mauritius prime minister's office said.

"An appeal is also made to the private sector for all flags to be flown at half-mast," it said in the note.

Singh, who served as the prime minister from 2004 to 2014 and widely known as the architect of India's economic reforms, died on Thursday night. He was 92.  India's relations with several key countries, including Mauritius, saw significant upswing during Singh's prime ministership.

Singh's last rites were held with full state honours on Saturday at the Nigambodh Ghat cremation ground in Delhi.  President Droupadi Murmu, Prime Minister Narendra Modi and King of Bhutan Jigme Khesar Namgyel Wangchuck were among those who attended Singh's funeral.

Bhutan's King Jigme Khesar Namgyel Wangchuck attended the funeral of former prime minister Manmohan Singh, a day after leading the Himalayan nation in offering prayers for the Indian leader at a Buddhist monastery in Thimphu.Separate prayer ceremonies were held for the former Indian prime minister at all 20 Dzongkhags or districts of Bhutan, according to the Bhutan government.

Bhutan's national flag was flown at half-mast across the country and at its embassies, and consulates abroad, according to the Royal Bhutan government.  A thousand butter lamps were lit at the ceremony held in Thimphu's Kuenrey of Tashichhodzong that was led by the King.

The prayer was attended by Prime Minister Tshering Tobgay, Indian ambassador Sudhakar Dalela, several members of the Royal family and senior officials of the Bhutanese government.

"As a mark of respect to the late former prime minister and in solidarity with the government and people of India, all national flags across the country and at Bhutan's embassies, missions, and consulates abroad are being flown at half-mast," the Bhutanese government said in a social media post on Friday.

India's relations with several key countries including Bhutan saw significant upswing during Singh's prime ministership.

India and Bhutan enjoy strong bonds of friendship based on goodwill, trust and mutually beneficial cooperation.

The basic framework of India-Bhutan relations is the 'Treaty of Friendship and Cooperation' signed in 1949. It was renewed in February 2007 when Singh was the prime minister.  The cooperation in the hydro-power sector is one of the cornerstones of the relations.

The ongoing cooperation between India and Bhutan in the hydro-power sector is covered under the 2006 bilateral agreement for cooperation and its Protocol signed in 2009.

The pact and the protocol were inked during Singh's tenure as the prime minister.

Meanwhile, Abed Elrazeg Abu Jazer, the charge d'affaires of the Palestine embassy in India, on Friday paid his last respects to the former prime minister and appreciated his support to Palestine.  Jazer said Singh played a key role in Palestine getting land for its embassy in Delhi.

"We have a history of relationships. He (Singh) met Yasser Arafat in 1991 when he was finance minister, he met (State of Palestine) President Mahmoud Abbas several times throughout his tenure," the diplomat told reporters outside the Congress headquarters where he paid tribute to the former prime minister on behalf of Palestine.  He also laid a wreath on behalf of the president of the State of Palestine.

"We had good relations with him (Singh). He met our president several times during his tenure. He also provided land for establishing the Palestinian embassy in Delhi, gave support to build the embassy, and also inaugurated it in 2012," Jazer said."We appreciate his support to Palestine, we are remembering his contributions. We stand with the Indian people to show our respect for the leader," he added.  Abbas visited New Delhi several times during the United Progressive Alliance (UPA) government.

In a speech before the UN General Assembly in September 2011, Singh had said India supported "the Palestinian people's struggle for a sovereign, independent, viable and united State of Palestine with East Jerusalem as its capital".
