Arizona Tribune - Security beefed up in Pakistan capital after deadly Lahore blast

The country has suffered a string of blasts and attacks since December, when a truce between the government and Pakistan's Tehreek-e-Taliban Pakistan(TTP) lapsed.

But Thursday's bomb blast -- in a busy shopping district of Lahore -- was claimed by the Baloch Nationalist Army (BNA), the newest of several separatist groups to emerge from Pakistan's biggest but poorest province, Balochistan.

Police spokesman Naeem Iqbal told AFP that security would be tightened in Islamabad, the seat of the government and home to dozens of embassies and other international institutions.

He said uniformed and plain-clothes officers would fan across the city, particularly in crowded areas such as markets.

Earlier this week a policeman was killed and two others wounded in a drive-by motorcycle shooting in the capital by two TTP militants who died in return fire.

The BNA said it carried out Thursday's Lahore bomb attack "in response to the killing of women and children by Pakistani forces in Balochistan".

Ethnic separatist groups have been waging an insurgency for years in the province, complaining they do not receive a fair share of its gas and mineral wealth.

In Lahore, officials raised the death toll from Thursday's blast to three after another victim succumbed to injuries.
