Twelve months after devastating floods submerged one-fifth of Pakistan and left some 2,000 people
dead, new weather warnings have been issued, with humanitarian organisations saying the country is still at risk.

The country has failed to invest in prevention measures since last year's floods and is vulnerable to another disaster this monsoon season, according to Oxfam, the British aid agency, wich has also called for more to be spent on reconstruction, suitable housing and early-warning systems.

"Pakistan needs to act now. Investing in measures today that reduce the impact of disasters is essential to save lives and safeguard development gains in the future," Neva Khan, head of Oxfam in Pakistan, told Al Jazeera on Wednesday.

Al Jazeera's Imtiaz Tyab, reporting from Thatta in Sindh province, said: "[The] United Nations is warning that this year alone [up to] six million people could possibly be affected by flooding."
