Aug 28 (Reuters) - The Taliban said on Saturday they were preparing a new cabinet as the U.S. evacuation nears its end and they expected that sharp currency falls and economic turmoil following their takeover of Kabul two weeks ago would subside. Zabihullah Mujahid, the movement"s main spokesman, made the comments to Reuters as the U.S. military winds down its mission to evacuate U.S. citizens and vulnerable Afghans and withdraw troops from Kabul airport ahead of the Aug. 31 deadline set by President Joe Biden. Mujahid condemned an overnight U.S. drone strike against Islamic State militants following Thursday"s suicide attack near the airport as a "clear attack on Afghan territory". But he appealed to the United States and other Western nations to maintain diplomatic relations after their withdrawal, which he expected would be completed "very soon". The exact timing of the formation of a new cabinet remained unclear. Reuters originally quoted Mujahid as saying the announcement would be made in the coming week, but in a voice message later he said the makeup of the new cabinet would be cleared "in one or two weeks". Responding to a question about whether any women would be included in the new cabinet, he said this would be a matter for the leadership to decide and he could not anticipate what their decision would be. There is mounting frustration in Kabul at the severe economic hardship caused by a plummeting currency and rising food prices, with banks still shuttered two weeks after the fall of the city to the Taliban. On Saturday, a statement from the Taliban said that banks were ordered to reopen with a weekly limit on withdrawals of $200 or 20,000 afghanis. Mujahid said officials had already been appointed to run key institutions including the ministries of public health and education and the central bank. United Nations officials have warned that Afghanistan faces a humanitarian catastrophe, with large parts of the country suffering from extreme drought conditions. The economy, shattered after four decades of war, also faces the loss of billions of dollars in foreign aid, following the withdrawal of Western embassies from the country. Mujahid said the economic problems being experienced would be eased once the new government was in place. "The fall of Afghani against foreign currency is temporary and it is because of the situation that suddenly changed, it will come back to normal once the government system starts functioning," he said.
