A US drone strike has killed at least five Islamic militants in Pakistan’s restive tribal region near the Afghan border, security officials said on Tuesday. The strike targeted a compound in the Mir Ali area of North Waziristan, known as a bastion for the Taliban and Al-Qaeda. The drone fired two missiles, they said. There has been a dramatic increase in US drone strikes in Pakistan since May, when a NATO summit in Chicago failed to strike a deal to end a six-month blockade on convoys transporting supplies to coalition forces in Afghanistan. Afghan’s Interior Ministry said on Monday 28 other militants had been killed and 54 others had been arrested by the Afghan army and NATO troops in Afghanistan.
