UNITED NATIONS (REUTERS) - The United Nations Security Council expressed deep concern on Wednesday (Nov 11) over increased violence across Myanmar and in a rare statement, agreed by its 15 members, called for an immediate end to fighting and for the military to exercise utmost restraint.

There are reports of a build-up of heavy weapons and troops in Chin state, suggesting an imminent army attack to flush out militia groups formed after the military ousted Ms Aung San Suu Kyi's elected government in a military takeover on Feb 1.

"The members of the Security Council expressed deep concern at further recent violence across Myanmar. They called for an immediate cessation of violence and to ensure the safety of civilians," the statement said.

Myanmar's ruling military has made no comment on the situation in Chin, a volatile border region that has become a forefront of resistance against military rule.

Myanmar has been paralysed by protests and violence since the military takeover, with the ruling military struggling to govern and facing armed resistance from militias and ethnic minority rebels allied with a shadow government that it calls "terrorists".

"The members of the Security Council... reiterated their deep concern at developments in Myanmar following the declaration of the state of emergency imposed on Feb 1 and their call on the military to exercise utmost restraint," said the statement, drafted by Britain.

"They encouraged the pursuance of dialogue and reconciliation in accordance with the will and interests of the people of Myanmar," the statement added.

The council also called for full, safe and unhindered humanitarian access to all people in need and the protection, safety and security of humanitarian and medical personnel.
