Pakistan arrests 'suicide bombers'

Four militants armed with grenades who were allegedly planning suicide attacks have been arrested in Karachi, Pakistani police said.

All four men, arrested in an eastern neighbourhood of the city, were said to belong to the outlawed Islamic group Jaish-e-Mohammed.

The four Pakistanis were identified as Riaz Uddin, Aziz Mubarak, Mohammed Kamran and Abdul Rehman.

The men said they had also carried out several robberies to get money to buy more explosives and weapons.

Police said they received a tip about the four, who headed towards a major thoroughfare where police believe they were planning to blow up a bridge.
