MUMBAI, India (AP) — India suspects two senior leaders of a banned Pakistani militant group orchestrated the deadly Mumbai attacks, officials said today, as Pakistan’s president vowed “strong action” against any elements in his country involved in the siege.

President Asif Ali Zardari’s made the pledge during a meeting with Secretary of State Condoleezza Rice in Islamabad. Rice said she is satisfied with Pakistan’s commitment to fight terrorism and its readiness to pursue any lead in the attacks that left 171 people dead in India’s financial capital.

Evidence collected in probes so far has pointed to two members of outlawed Pakistani group Lashkar-e-Taiba as masterminds in the attacks, according to two government officials familiar with the matter.

The men, Zaki-ur-Rehman Lakhvi and Yusuf Muzammil, are believed to be in Pakistan, the officials said.

Lakhvi was identified as the group’s operations chief and Muzammil as its operations chief in Kashmir and other parts of India.

The lone surviving gunman in the assault told police Lakhvi recruited him for the operation, and the assailants called Muzammil on a satellite phone after hijacking an Indian vessel en route to Mumbai. During the attacks, the gunmen used mobile phones taken from hotel guests to place calls to the Pakistani city of Lahore.
