President Barack Obama has opposed drone strikes in Quetta, the provincial capital of Balochistan province, fearing that this will bring huge mass casualties. The Obama administration officials told US news journal that the president has sided with political and diplomatic advisers who argue that widening the scope of the drone attacks would be risky and unwise. Obama is concerned that firing missiles into urban areas like Quetta, where intelligence reports suggest that Taliban leader Mullah Mohammed Omar and other high-level militants have sometimes taken shelter, would greatly increase the risk of civilian casualties. The White House has been encouraged by Pakistan's own recent military efforts to root out militants along the Afghan border, and it does not want to jeopardize that cooperation, officials said. Sources told magazine, the meeting mulled over the surge in drone strike on Pakistan but no final decision could be reached and the meeting agreed further discussion over the issue.
