WASHINGTON - The Indian city of Mumbai is trying to move past last week's terror attack and turn things back to normal.
But for many Indians, mourning has turned into anger against their nuclear neighbor Pakistan.
Meanwhile, the U.S. is adding pressure, telling Pakistan it must cooperate in the investigations.

Reaction Mixed Following Siege
Nerves are continuing to run high, even as security officials in Mumbai cleared the final site of last week's attacks.
Some of the survivors, like Farzad Jehani, have shown an uncanny resilience.
"If I don't open those shutters then that means the terrorists have won. I don't want that," Jehani said.
Others are calling for revenge.
"When it is war, then you should behave like war. Enemies are enemies and enemies should be killed," said Mumbai parliament member Bharat Raut.
Some survivors who returned home to safety still have difficulty describing what they went through - including the loss of friends and colleagues.
A total of 172 people were killed during the 60-hour siege, including six Americans.
Hundreds more were wounded in the brazen attack now believed to have been carried out by a Pakistani militant group known as Lashkar-e-Taiba.
Investigators have been collecting information from the lone survivor, who says their plan was to kill 5,000 people in India's economic hub.
"He's been talking, giving investigators a fairly precise idea of when they left Karachi, how they changed ships twice mid-sea, what their instructions were, how they trained using high resolution satellite maps," said Praveen Swami, editor of The Hindu Newspaper.
Pakistan denies any involvement.
"The important thing is that the state of Pakistan, the government of Pakistan, the military of Pakistan, and Pakistan's intelligence services are not in any way involved in these attacks," insisted Hussain Haqqani, Pakistan's ambassador to the U.S.
US: Pakistan Must Cooperate
Ahead of a scheduled trip to India this week, Secretary of State Condoleezza Rice said she expected "complete, absolute, total transparency and cooperation" from the government of Pakistan.
Some believe the terrorists may have had help from elements of Pakistan's spy service.
India has warned that the attacks dealt a "grave setback" to normalizing relations with its nuclear neighbor. The two countries are bitter rivals that have fought three wars since 1947. And last week's attacks and suspicions only raise tensions further.
