Cairo ( CNN ) -- Just two weeks after the Egyptian military ousted President Mohamed Morsy , the country 's interim leader Tuesday swore in a new cabinet that excluded members of powerful Islamist parties that came to political power in the country 's first democratic elections . The news followed state-run media reports that at least seven people died and more than 260 were wounded in overnight clashes in Cairo , where near-daily battles between Morsy 's supporters and those opposed to his rule have broken out since he was deposed on July 3 . Outside of the capital , soldiers seized 35 rockets and a machine gun that authorities say were bound for Cairo , according to a military spokesman . The weapons were discovered in a truck that was stopped while trying to make its way through the Cairo-Suez checkpoint , the spokesman said . The new government of interim President Mansour Adly is part of a military-backed plan that dismantled Morsy 's government and suspended the constitution until a new one can be drawn up and new elections can be held in six months . The appointment of Adly 's new cabinet members , which include Hazem El-Beblawi as interim prime minister and Nobel laureate Mohamed ElBaradei as interim vice president , is likely to do little to cap the growing anger among Morsy 's supporters , who have refused to accept the new government . Cabinet posts were offered to the Muslim Brotherhood , of which Morsy is a member , and the Salafist Nour Party , presidential spokesman Ahmed El-Moslemani told Al-Masriya TV on Tuesday , adding that everyone should be included in the political process . `` We are not alienating anyone , and we expect most Islamist movements to take part in reconciliation , including the Muslim Brotherhood , '' he said . The Muslim Brotherhood , however , refused to participate . Ahmed Ali , spokesman for the Muslim Brotherhood , recently responded to Mansour 's invitation to include the group in the transitional government . `` More than 700 of our members arrested , broadcasters shot down and people killed in front of the Republican Guard . It is impossible to speak under the current circumstances , '' he said . `` There is no way to have negotiations . '' Even as the Egyptian military promises a transition to a civilian government , there were indications that it planned to have an active role in the formation of the new government . Gen. Abdel-Fatah El-Sisi , the nation 's military leader , also adopted the title first deputy of the interim prime minister , according to state media . Among the other appointments to the 34-member cabinet , according to the state-run Middle East News Agency ( MENA ) : . Ahmed Galal , a liberal economist educated in the United States and a World Bank veteran , has been appointed as finance minister , and Hisham Zaazou who will retain his post as tourism minister . The news of the appointments came as Egypt 's top prosecutor , Hesham Barakat , opened an investigation into whether Morsy and 18 senior Muslim Brotherhood leaders made a jailbreak during the early days of the 2011 popular uprising that toppled Hosni Mubarak . Among the allegations , according to state-run EGYNews : Morsy and the others were helped in their escape by elements of the Palestinian militant group Hamas and Lebanon 's Hezbollah along with other Salafist and Muslim Brotherhood supporters . The Muslim Brotherhood was outlawed during Mubarak 's iron rule , and its members were routinely jailed . Additionally , authorities are investigating Morsy and several leaders and supporters of the Muslim Brotherhood over accusations of spying and inciting the killing protesters following his overthrow . Authorities have have frozen the assets of more than a dozen people in an investigation of violence in Cairo . The investigations are widely viewed by Morsy 's supporters as an attempt to discredit him as the legitimately elected leader of Egypt . Morsy , sworn in in June 2012 as Egypt 's first democratically elected president , has been detained since his ouster . El-Moslemani said Morsy is `` in a safe place , and he is being treated with the utmost dignity that suits a former head of state , and when it comes to the legal charges , I will leave this to the official spokesman of the public prosecutor . '' The United States and other Western nations have called for Morsy 's release . U.S. State Department spokeswoman Jennifer Psaki has labeled the detentions of Morsy and members of the Muslim Brotherhood were `` politically motivated '' and urged the military to let them go . On Monday , U.S. Deputy Secretary of State William J. Burns emphasized the need for stability and tolerance as he became the first U.S. official to meet with Egypt 's interim leaders . Burns urged leaders to end the violence , according to senior State Department officials , adding that `` only Egyptians can determine their future . '' Egypt has long been a close ally of the United States . The country gets $ 1.3 billion in annual U.S. military aid . CNN 's Roba Alhenawi contributed to this report .
