London, July 7: Britain on Monday marked the anniversary of the 2005 London suicide bombings which killed 52 people amid an uproar over reports that a brother of one of the suicide bombers was given a free gap-year trip to Pakistan where the terrorists were trained for the attacks.

Relatives of those killed in the bombings which tore through three underground trains and a bus, on Monday condemned the “insensitive” trip, which was designed to improve cultural ties and “bridge the gap” between communities in Pakistan and Britain.

The bomber’s brother, who has not been named, was flown to Pakistan courtesy of Projects Abroad, a company specialising in gap-year travel.

He visited Islamabad and neighbouring provinces near where the bombers plotted jihad at notorious terror camps.

In 2004, Shehzad Tanweer, 22, and ringleader Mohammed Sidique Khan, 30 had secretly travelled to the country to learn al-Qaeda terror techniques.

In Pakistan they stayed in al-Qaeda safe-houses in Islamabad, Rawalpindi and Lahore and learnt how to make bombs.

With Hasib Hussain and Jamaican-born Jermaine Lindsay, they blew up the three underground trains and a bus on July 7, 2005.

Survivours and families of victims joined London Mayor Boris Johnson and Tessa Jowell, the government’s London Minister, laying flowers— the time when the first three bombs went off.
