Abuja: A minute's silence was observed in memory of Kevalkumar Kalidas Rajput, the Gujarati youth who was killed in a recent terror attack in the African country, at a ceremony here to mark India's 63rd Republic Day.

The event was officiated by the High Commissioner to Nigeria, Mahesh Sachdev, who hoisted the tricolour and read Prime Minister Manmohan Singh's message.

Sachdev said that six other Indians, who were injured in the attack, have been flown to the country for medical attention.

Kalidas, who worked for the Kano-based firm, M/s Relchem, lost his life in the coordinated bombings and shootings on January 20, which left over 160 people dead.

The bombings which numbered up to 20, caused pandemonium in the metropolis and was followed by shoot-outs between militants and security agencies, especially in the eastern Bompai district of the city.

Nigerian Islamist group Boko Haram has claimed responsibility for the attacks.

Speaking on the occasion, the High Commissioner said the commitment to democracy is one of the high values that India shares with Nigeria.

"These shared ideals have provided the basis for cordial and substantive ties," he said.
