The leader of India`s main opposition party urged the government to "avenge the repeated terror attacks" and hit back at arch-rival Pakistan, the Press Trust of India said on Thursday, AFP reported.

Speaking a week after coordinated Islamic militants in Mumbai -- which India has blamed on a Pakistan-based group -- Bharatiya Janata Party (BJP) chief Rajnath Singh said patience had run out.

"The government should consider taking some measures against Pakistan. Enough is enough. There is a need to avenge the repeated assault on our people and democracy," he was quoted as saying by PTI.

He said the Hindu nationalist BJP would back government plans to increase security after the assaults, during which militants laid siege to hotels and other sites in the city for 60 hours.

The attacks left 172 people dead, according to official figures.

"The BJP will support every honest initiative that the central government proposes to fight terror," Singh said.

He reacted angrily to Pakistan`s assertion that "non-state players," and not the government in Islamabad, were to blame.

"If the Pakistan government does not have full control on activities taking place on its soil, then the international community should consider the implications of Pakistan`s nuclear arsenal and facilities falling into the hands of non-state players," Singh said.

India hauled in the Pakistani ambassador earlier this week and demanded Pakistan arrest and extradite 20 terror suspects, including the founder of the Lashkar-e-Taiba group at the centre of investigations into the attacks.

On Wednesday, Foreign Minister Pranab Mukherjee said that all options were open to deal with Pakistan.
