Pakistani Prime Minister Yousuf Raza Gilani held talks with Iranian President Mahmoud Ahmadinejad in Tehran Monday aimed at boosting bilateral ties.

Mr. Gilani, who is heading a high-ranking delegation, said after the talks the two sides agreed to enhance cooperation in a wide range of fields, including the fight against terrorism, trade, economy, and the Iran-Pakistan gas pipeline project.

On Sunday, Iran pledged to donate $100 million for the victims of the latest flooding in Pakistan. Prime Minister Gilani thanked the Iranian government and people of Iran for their assistance.

Iran and Pakistan have recently worked to boost bilateral relations, with officials from both countries paying exchange visits.

Pakistani President Asif Ali Zardari visited Tehran in June and July, while Iranian Foreign Minister Ali Akbar Salehi paid a two-day visit to Islamabad last week to discuss the construction of the pipeline that will allow energy-hungry Pakistan to import natural gas from neighboring Iran.

The $7.5 billion pipeline will connect Iran's South Pars gas field to Pakistan's Baluchistan and Sindh provinces. The project has seen numerous delays and is opposed by the United States, which has placed economic sanctions on Iran due to suspicions about the country's nuclear program.

Pakistani officials say the planned pipeline will supply the country with about 21 million cubic meters of gas daily by mid-2015.
